We are currently experiencing an issue with our Netware clients. After
what appears to be a successful login they loop back to the login again.
Generally after 4 to 7 attempts the login actually works and the desktop
comes up. It is hit or miss. The same machine that does this may not do
it the next time you reboot.

Any ideas?

Novell client is 4.90 SP1 and it in the image we deploy.
