Hi Ron,
Your suggestion helped, but not completely! I can now browse the web but I
still get the error messages at startup (missing vnetbios.vxd, vredir.vxd,
dfs.vxd as well as the msnp32.dll error dialog box). Also, the system is
unstable. It often reboots after I close IE. It also sometimes hangs on
reboot after the missing dfs.vxd message.
Do yo have any further suggestions?
TIA,
GB

Hi,
As a followup, I used System File Checker to restore the 3 missing ".vxd"
files and now I do not get the error message.
I tried restoring msnp32.dll to the Windows\System directory but that did
not get rid of the error box, probably because destination folder was
incorrect.
Any further help would be greatly appreciated.
TIA,
-GB

The system folder should be the correct destination.
This article discusses the error message still appearing after extracting
the file:

Hi Ron,
Your last suggestions seemed to have done the trick. Removing and
reinstalling "Client for Microsoft Networks" appears to have solved it.
Thanks a lot,
