Outlook 2000 hangs periodically when using Netscreen 5xp

[Blackvette]

AAGGGGGGHHHH!!!
This is driving me nuts!!! Outlook works great for 2 or 3 hours and then bam...It just freakin hangs!! If I let it sit for over 15minutes then eventually it comes back...

This ONLY happens with the Netscreen Firewall.. If I disconnect it and use a software based tunnel I have no problems...

PLEASE help if you can...

telnet to the netscreen and try this cli command:

set flow tcp-mss

save

Tons of my users were having this problem with outlook. seems to be due to fragmentation. this'll limit the maximum segement size and should keep outlook from hanging.

Thanks
I already had
SET FLOW TCP-MSS 1392

Is this not enough?

Also, Overnight my Outlook asks pops up with the Password window. I see it in the morning..Something is making it reauthenticate again too..

Try

set flow path-mtu

This was recommended to me by netscreen to cure performance problems with ns25 to ns5 vpn

I'll try it right now.. Thanks.
I'll let you know how I make out...
