All client computers, as well as the servers, are members of the AD domain.
Because all computer accounts stored there, there should be no reason to add
them in workgroup manager...

It's not that it isn't working at all. It's working, but slow and with error

Update: I figured out that it seems to be a client problem, or to be
precise, a MS Office problem. The described erroneous slow behaviour only
happens if I try to browse the server folder by accessing it thru an UNC
name (\\servername). If I map a drive letter to that share and access the
server by this network drive, it's all very quick. I always thought,
acessing a network share by network drive letter or via UNC path is the
same, but obviously, it is not...
