Hi,

Had the following scenario:

Two (separate customers) with sbs2000. Downloaded and installed SBS SP1
(Not 1a) on both machines. After installing the systems slowed down
considerably. Most noticably on the applications they were running, Syspro
Accounting (Encore) on the one using flat files and not SQL, and a Personnel
management program on another using ODBC to connect to the database on the
server again not SQL only the database was on the server and not the app.
Outlook would also be slow and sometimes a message would pop up stating
trying to find Exchange server. LAN is 100MB Ethernet.

The only common program, either than SBS2000, on both systems was Trend Anti
Virus.

Removed the Trend and system 1 was fine for a week, then slowed down again.
Reinstalled Trend, but with the program updates , no difference in
performance.
Checked utilisation on CPU, Memory, HDD, Processes etc and all were well
within tolerances.

I then re-installed System 1 from scratch, applied the individual service
packs (not sbs sp1) and everything is fine.

Questions

Has any body else seen this?
If so what was the cause?

What might be important is that both servers were single processor P4
servers running IDE Drives
One had the Intel Woodruff serverboard and the other the gigabyte
serverboard; P4 2,53; 512MB RAM
Both have Promise RAID 20267 (RAIDO,1) on board and both were configured for
disk mirroring

Any help would be appreciated as System 2 still needs to be fixed!

RE: SP1 for SBS2000 - slows system down by msadoff

Hi Peter,

Did the slowness seem related to client/server connectivity? If so, what
version of Windows are the client computers running? Also, what Windows
service pack did you have on the servers prior to the SP1 update?

The most notable change included in SBS 2000 SP1 - that was *not* included
in individual service packs for Windows, Exchange, ISA and SQL - was
disabling SMB direct hosting. They intended this change to correct some
network browsing errors on Windows 2000 and XP Pro computers, but the
change had unintended effects on some systems. Also, it disabled
functionality originally designed to improve connectivity. Is System 2
still having problems? If so, I can give you the steps to re-enable SMB
direct hosting, if you would like to try it. Let me know.

Sincerely,
