My network has three NW5.0 (with SP6a). Recently, I added one SBS6.6 server
(OES 6.5 with SP5) for new GW7. After that, many users have intermiettent
problem accessing their files that stored on one of the NW5 server. When
user try to access a file on NW5 server or try to save a opened file back to
server, they have "Access denied". When they try again after a few seconds,
it works. Looks like the user lost the connection and getting "access
denied" and the client reconnected to server after that. Most of the user
are using 4.83 (SPx) and I updated a few user to 4.91SP2. Could someone
help, please?

Thanks very much,
