I have 5 pc's accessing a samba server. only ONE individual has this

When opening files in lotus, it will open 90% of the file, then hang.
We get "program not responding" on the pc... but if you leave it for
5-10 minutes, the file will eventually open.

I'm using SAMBA vs 2.2.7a
on Redhat Linux 2.4.20

Any ideas? there arn't any errors in the samba log file.

YOu can go to any other pc and open these files fine, but from this one
pc... it hangs almost every time. File size makes no difference.
