Windows XP sp 2 Firewall blocking UDP transport?

Hello,

I've been fighting an uphill battle with new mail notifications not
being pushed to my clients. to this point, i'm going to suspect that the
windows XP service pack 2 firewall (on my default) on my network is causing
the problem. It only seems to effect people randomly... usually an exchange
reboot will get it moving a little faster.

i tried all registry hacks for outlook RPC updfixes and forced
polling... nothing seems to work...

Does anyone know which UPD ports i should allow for my xp firewall? it
seems that all i can find on exchange ports are TCP. I would really like to
figure out the issue with new mail notification taking anywhere from one
minute to never coming, unless the client's outlook is refreshed.

Thanks.
 
Which version of outlook and do you have the latest sp installed?

Do you have the XP firewall enabled? If the network is behind a firewall,
you don't need the XP version on the local machines.

I agree with Diane, but if you must leave the Windows Firewall enabled for
some reason, open up full access on the local IP subnet. I don't have SP2
here so I can't tell you exactly where this is, but you might get more help
in m.p.windowsxp.general.
