Outlook 2000 freezing with SBS 2003

[J Smith]

Hi,

I just upgraded a network from Small Business server 4.5
to Small Business Server 2003.

Everything seemed to be running ok, but people running
Windows 98 with Outlook 2000 now report intermittant
freeze ups. Outlook will hang after startup - sometimes
after waiting for 5 minutes it will begin to work again,
sometimes not.

Users running Windows XP with Outlook XP or Outlook 2003
do not see any problems.

There are no errors in the server's application logs. I
have applied all the Win98 updates, as well as the Office
2000 patches.

Can anyone make any suggestions?

Thanks

J
