prefix of email addresses appears in CAPS. How do I make it in lower case,

$
0
0

I have a client who have this strange not causing any issues with services yet a problem. All the users email addresses have prefix in capital letters for instance USER@contosso.com and need it to be user@contosso.com. I am well aware that email addresses are not case sensitive but still need it in lowercase. 

I've checked in AD, OWA mailbox policy and Email address policy in office 365 but I couldn't find anything helpful.

Everything appears to be in place but still prefix of the SMTP address appears in CAPS.

Any help is appreciated.


How to run specific application like IIS without administrator rights

Hi

We have setup AD DS and apply GPO.

Users systems are joined to domain also.

There are some application like IIS which are currently running as administrator.

I dont want to run IIS or like applicatiions as administrator.

How I create a GPO so that domain users can run these type of applications without administrator rights.

Also I don't want to give users Domain Admin rights.

Hi Guys,
Bare with me I won't be as technical as even a fraction of you here.

I am looking at deploying a completely new windows environment DC/AD etc. There is currently no infrastructure setup and I have been looking at different deployment possibilities. Would be looking at setting this up for multiple sites in the UK, NY & LA

I am looking at possibly a hybrid solution (On-Prem & Cloud) via AWS or Azure. Firstly as I haven't been exposed to a windows domain environment hosted in either, does anyone have any recommendations or insight into either they could share? 

Secondly, I was wondering if there was a purely cloud-based option using VM's in either AWS or Azure? I am obviously opposed to setting up such an environment due to low guaranteed availability & bandwidth constraints of everything using the IGW.

The business would like the possibility explored and there are multiple DaaS which don't offer GPO, which is a deal breaker.

Users:

UK - 70, NY - 15, LA - 8

No existing domain or windows services currently running (Except DNS)

If you need to know anything to get a better feel of our need please ask.

Windows Server 2016 out of its domain not allowing anyone to log in to it neither AD users nor local users.

This morning the server was preventing users from logging in so I went to check and according to the attachments I will post down below It appears online and responds to ping requests, but on its screen it does not have any available network connections and does not allow Administrator log on neither AD users to log in to the network nor access the folders because it says something is wrong with their credentials, which in fact is not. Somehow the server left the domain and maybe it's on a private network I suppose.

What has already been done:

Start with the last valid configuration (not resolved)

Log in safe mode (starts in protected mode and does not let the administrator do anything)

What was not done:

Exploit to Reset Password with Vulnerability CVE-2017-0213_x64
Other Hacking Methods ...

Frequently Asked Questions:
Is the server licensed? Yes, It is.

What is the Server Version?
Windows Server 2016 Standard

Does the server have UserCals and Are they properly registered and enabled?
Yes.

Is the network cable connected to the server?
Yes

Is the Switch Connected to Computers?
Yes

The network cables have signal?
Yes

Am I on the same server network?
Yes

Am I entering my credentials incorrectly?
No

Cancel AD DS Promotion on Windows Server 2016

$
0
0

On one of our servers, somebody (who probably only was supposed to install the AD Management Tools), instead decided to install the AD DS Role on one of our Windows Server 2016 boxes!

At the moment, it displays (in Server Manager):

"Post-deployment Configuration:

Configuration required for Active Direct Domain Services at <servername>

Promote this server to a domain controller"

Can we just remove the AD DS Role, or do we have to continue with the promotion to a DC and then demote it afterwards?

Many thanks.

Conflict in domain name between two containers Users and Builtin

$

We have windows server 2016 installed with ADDS running on it. Last year they have upgraded the server from Windows 2008 R2 to Windows 2016 during this process they have renamed the server name eg:test (old server name) to test1. Now in our ADDS if  groups inside "builtin" container are added in NTFS permission on a folder shows new domain name eg: test1\Users,but when Domain Admin group in "Users" container added to NTFS shows test\Domain Admins(olddomain name).But the members of Domain Admin group are not able to access the folders though the group as full previledges on the folder. When same user added to Users group inside the Buildin container the  members are able to access it. I predict this is because of the naming conflict between the two container and I am not really aware of the process they have taken during the migration.Please provide your valuable advice and  on how to approach this issue.




User rights to download

The Users in my Domain only have User rights. However some of our users needs rights to be able to download files from the Internet and open them. They cannot do that with user rights. They get prompted for an Admin login everytime. What group can I add them to that will still restrict them from doing anything malicious but yet allow them to download and execute files??

Hello, All!

How i can found users in some OU in domain in case when bindDN it is a root of domain?

As far as i understand i must use https://ldapwiki.com/wiki/LDAP_MATCHING_RULE_DN_WITH_DATA for this.

I'm stuck at creating filter. My variant is:

(Common-Name:1.2.840.113556.1.4.2253:=S:4:myou:dc=td,dc=local)

What i must use at place where "Common-Name"?

What i must use at place where "S:4:myou"?

Will be glad for any information related to this issue.

New DC's in an old broken environment

$
0
0

I've had a look at other topics on this but none seem to answer my query completely.

We have two DC's that have multiple profile problems so after a lot of thought and planning we've decided to build two new ones. 

The current DC's are on server 2012 R2 but have the 2008 configuration as they were moved over in a "as is" state. They are VM's sitting on the local Hyper-V hosts. The site has a cluster environment complete with several VM's including a 2016 Exchange server. 

The new DC's will be Server 2016 Standard VM's also sitting on the 2 HV hosts. 

I need a little guidance on what is the best way to introduce the two new servers - add a new domain or bring in the new one to the broken domain?

Adding the new DC's to the existing domain will just copy all the problems across with it won't it? 

A tidy up will be completed but I can't see doing it like this would be beneficial. AD will be cleaned up after this removing old users etc and new profile (Roaming) locations on the new file server will be created. User data will then be moved to the new File server.

The other way is to create a new domain, enable a trust between them and build AD from scratch. However, this is a cluster environment so not sure how this would work when it comes to demoting the old DC's. What if we lose connection completely? We'll obviously need to manually add in PC's to the new domain but it's the cluster and current setup I'm concerned about.

Having said that I think having a new domain is a better option so it doesn't pull the rubbish over but I don't know enough about it to make a decision.

The time line is to complete before the end of this year so any help here would be greatly received.

Many thanks

Azure AD Connect Microsoft PolicyKeyService Certificate Authority

$

Dear All,

Since a few weeks (after some adjustments in SCOM) we receive several alerts on Azure AD Connect Servers (different tenants) regarding a certificate warning.

Apparently Azure AD Connect uses/generates this certificate. Certificate information:

Issuer: Microsoft PolicyKeyService Certificate Authority
Validity Period: 2 years
Hashing algorithm: SHA512

On the Certification path tab it shows "The issuer of this certificate could not be found", which causes the SCOM alerts. I presume this is a self signed certificate, since it's the only item in the chain on the cert path tab.

If somebody could enlighten me with what purposes this certificate is serving, and how to resolve the warning?

Thanks in advance!

No NETLOGON or SYSVOL Shares in New Domain Controller

$
0
0

I have a Server 2016 functional level AD with 2 DCs.  Couple months ago I installed the second DC and only recently realized it lacks the NETLOGON and SYSVOL shares.  Last night I demoted the DC and removed the ADDS role.  Then re-added the ADDS role and promoted the server to a DC.  This was all done with no 3rd party firewall and the windows firewall off, and being logged on as a Domain Admin.  DCdiag throws errors about replication not working.  I have been unable to get to the root cause of those errors.  What do I need to do to make this DC healthy?  Below are some interesting parts of dcdiag /v.  Thanks.

Transfer Schema Master Role to Child Domain

$

Hi, our current set-up in our AD Forest is:

Parent Domain - Domain1.local - DC1 hosts all roles:
Schema master role
Domain Naming Master
PDC Emulator
Infrastructure Master
RID Master

Child Domain - Child.Domain1.local - 2 DC's, host between them:
RID Master
Infrastructure Master
PDC
However the following:
Schema Master and Domain Naming Master roles are on forest root domain, above - DC1

We want to install an Exch 2010 server in child domain, setup complains of schema master role being in different domain (parent domain). Is it possible to transfer the schema master role to a DC in child domain?

Thanks

Sarah



Global Groups vs Universal Groups vs Domain Local - Differences in brief?

$

Hi folks.  I'm working on my 70-640 test prep and I'm running into the differences in the different types of groups and I'm getting a little confused.  I've always just used universal groups and never had any problems and was wondering why use something like a global group instead of a universal group.  Also, what is the piont of the domain local group?  I've never used it and I'm having a hard time based on what I've read in telling the differences.  Thanks.
