Outlook very slow

[GB]

Hi All,

I have a client with a SBS2k network, win2k workstations and office xp. One
workstations seems to have problems when sending e-mails to the outside
world, it takes about 15/20 sec. for the message to go through the outbox.
All other PCs are ok, I have updated everything on this specific machine,
all office and windows updates possible, still no joy.

Any ideas??

thanks in advance
