samba - Jan 2005 - Upgrade Recommendations and/or Tips - SAMBA 2.2.8 to 3.0.?

Hello all,
 
Pretty new to the whole SAMBA scene.
 
I've been using it for ~3 years now, but haven't had many issues before
now.
 
I'm running SCO Unix 5.04 and am currently running SAMBA v2.2.8.
 
We use SAMBA simply has a simple Windows-to-Unix share...
 
With MS release of security updates KB885835 and KB885386 our software
doesn't work completely.
 
Any hints on what our next step should be?
 
There seems to be a lot of "issues" with 3.0.10.
 
Is that the only release that "fixes" this MS update problem?
 
Thanks for the information and guidance.
