Hi Dennis,
update to 6.5d fixed the error message and the permissions and the empty permission tabs, now everything seems to work as expected.
Scaling issue is confirmed -> my fault. thanks for the hint.
1) "Error on 6.5b" - Can you tell me what screen this is? It looks like [vCenter] -> Configure -> General, is that right? -> Yes this i right!
And yes Page loaded successully in 99 out of 100. i guess its an issue in 6.5b on Win with ad as machine account.
But heres the point i wasted 2 days seeking browser issues because i am not shure anymore if this effects are browser related or vcenter bug related.
Which is a mess for real. And thats what this Topic about you take us the chance to decide if its a configuration issue or bug in vcenter because we see 1000 errors in different browsers and 999 just dissappear on refresh / reload.
