Event ID: 1058 and 1030

Hi,

I have a client case where our client has Windows Server 2003 AD environment. On one member server (not DC, this has Terminal Server role) I receive following error messages in Event Viewer Application log every time I run "gpupdate /force":

Event ID 1030

and Event ID 1058

I have hidden client domain name as per security reasons. Let's call domain as "domain.net". Let's say this problematic client server name is for example "SRV01" and Domain Controller name is "DC01".

Here is how I have trobleshooted this issue:

1. Tried to ping domain.net - reply from on of the DC's (DC01) 192.168.100.100 (for example)
2. Open \\domain.net\SysVol\domain.net\Policies\ share with Windows Explorer from SRV01 - working ok
3. Open \\domain.net\SysVol\domain.net\Policies\{DA12E8D1-8712-40C6-BC86-91084100ED4A}\ share with Windows Explorer from SRV01 - not working (error message: Windows cannot find '\\domain.net\SysVol\domain.net\Policies\{DA12E8D1-8712-40C6-BC86-91084100ED4A}\'. Check the spelling and try again, or try searching for the item by clicking the Start button and then clicking Search.)
4. Open \\DC01\SysVol\domain.net\Policies\{DA12E8D1-8712-40C6-BC86-91084100ED4A}\ - working ok!
5. Clear client MUP cache (on SRV01) with command: "dfsutil /PurgeMupCache" - no help

Can you figure out based on this information what is the problem here? It seems weird to me that when using the domain name this folder does not open but when using the DC name instead of domain name, it does open. I have managed to repeat this problem (step 3.) on other servers as well but on some servers this works just fine. Any ideas what is causing this problem?

Thanks in advance for your answers and help!

Best regards,

Toni
