[cvsnt] how to improve the stablity of connection for the remote users

[zpshen]

hi,
   here I have a CVSNT server installed on a Windows2003. and we have  
several developers
in another city, who use TortoiseCVS to connect to the cvs server, and we  
use pServer protocal.
   my problem is that it seems the connection is not stable enough, the  
developers often complain that the 'update' often stoped with some red  
error messages aften they update some files (not completely).
   So I want to ask that:
1, if it would be better if I change another protocal, if yes, which one?
2, if it would be better if I set the compression in the server setting?


Thank you in advance!
Peter
