can't seem to checkout from my pc running cygwin on XP

[Please]

Running cygwin in rxvt with cvs 1.11.17 on XP -- all up to date.  

Can someone suggest a possible cause/fix for this?

This sort of thing has happened on every checkout I've tried from our local 
repository.  I tried several different top level directories and same thing. 

I've checked out large projects from public repositories with no problems.

Thanks.
