Outlook hanging for remote users after Blaster...?

[Nick]

I am getting reports from many of my users that when
connecting from home using VPN, their Outlook hangs and
shows 'Not Responding'. This has only started happening
since the Blaster outbreak last week. Would be interested
to hear of anyone else has the same issue....thanks

Nick,

My guess is that if you take a network trace of the logon sequence you would
see port 135 getting blocked.

For VPN users, the simple workaround (usually) is to modify your Hosts file
to include
something like the following:

<internal IP of Exchange server> <FQDN of Exchange server>

Hope this helps.
