EPDM 2009 SP3.0 and Windows 7 64-bit Can't login??

What am I doing wrong?

When I try to login in to the project vault EPDM says: "Could not connect to the archive server "xxxxx" for the vault "Projects"

I know Enterprise 2009 is not officially supported by Windows 7. But the strange thing is that on several other windows 7 machines it's working perfect.

Anyone out there who can help me?
