2000 SP4 w/ Netware

I have an issue on multiple machines where after the install of SP4, I
cannot download my roaming profile from a Netware Server. Uninstall
of SP4 allows me to login just fine. I've seen others post similar
complaints and was wondering if this is a known issue.

Thanks for your help.

Setting:

Windows 2000 SP2 + SP3 before install of SP4.
Netware 5.1 SP6
