Outlook web access using port 137???

B

brece

I have a strange issue, not sure hwat the issue is. I have remote users out
at client sites attaching to the client's internet connection and using
Outlook Web Access. All the users are doing is checking and writing e-mails
but several times during the day, My firewall reports traffic from the Public
IP address of our client and blocks the traffic.

That's good, but my firewall is also set to autoblock sites that send
blocked port traffic on port 137. So then they can't use OWA until I clear
the block.

Has anyone heard of OWA using port 137 for anything? Or do you have any
other ideas? Would the client (the corporation not the computer) attach port
137 traffic on the way out? Please help, I am baffled.
