We actually encouter a strange problem with our WIndows 7 clients.
We have a 2003 domain, with only one forest, we have added a 2008 R2 domain controller a few days ago, everything works well.
Today, when we try to modify users passwords, we recieve the following message : "The security database on the server does not have a computer account for this workstation trust relationship", it appears only on Windows 7 clients.
I've found some solutions (this one for example, http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/Q_23258126.html
) but they doesn't work.
Microsoft give us some solution too (http://technet.microsoft.com/en-us/library/ee849847(WS.10).aspx
but with no resluts too.
Any idea ?
