Computer icons represented as users in the group

Hello everyone,

I have this stupid issue...

So, I have security global group which has arround 3000 computer objects and through ADUC when I look at the group and go to Members tab all computers have user's icon.

We manage group membership with the powershell script. Everything is populated correctly, I have checked backlinks on computer objects and repl metadata for a group. So membership is fine, no issue.

And that would be the end for me, but not for the customer. So if you stumbled on something like this let me know. The only thing I had found is KB281923 but that doesn't apply - not the same issue.

Same issue in all environments regardles of DFL, FFL or OS version. Have just checked 2008 R2 FFL.

Thanks
