CVS checkout / update hangs in Register

[Roger Tinembart]

Hello CVS Gurus

I have a strange problem: If i try to checkout a project from my
Laptop with Windows 2000, cvs starts working and then hangs. The
strange thing is that when i try to do the same from my PC with
Windows NT, it works perfectly. If i checkout the project under NT and
copy the files to the Windows 2000 Laptop, i can do a cvs update. If i
delete one file and do the update again, it starts working (comparing)
and then hangs when it should update the deleted file.

Configuration:
Server: SUN Solaris 5.6, CVS 1.9.22
Client 1 (working) : Windows NT 4.0, Servicepack 6a, CVS 1.10
Client 2 (hanging) : Windows 2000, Servicepack 2, CVS 1.10

Trace:
C:\TEMP>cvs -t checkout hydra/Client

S-> Register(IniEx.h, 1.3, Mon Dec 17 07:00:51 2001, ,  )
... now it hangs

Thank you for your help.
