SP1 Broke my Server 2003 with Exchange server 2003

Help.

I have server 2003 with exchange server 2003, from the day I updated to SP1
I seemed to start having problems.



For one the system is configured with two IP addresses, one for the internal
network and the other for our DMZ, the DMZ IP address has traffic forwarded
to it so that I can serve http email for OWA and so the server can receive
email on port 25.



It seems that now this doesn't happen. If I attempt to connect from outside
I just sits there, no connection is made what so ever.








Backup

i will guess that uninstalling sp1 will fix the issue
i had removed sp1 from one server after my trendmicro products that use a
web interface didn't work properly; they would fail with numerous cgi
application errors. the interface was fine after dumping sp1

Well I attempted to correct the problem "AGAIN" this will be the 2nd time I
had to do this.

What I did was remove all the IP addresses from the network interface, then
I added them once more and wow look at that it's working again. I did this
one time before, about 5 days ago. I want to see if this problem happens
again as I don't know why I happens in the 1st place.



I know some might say well you're traversing two subnets in one card. etc.
But it should work with out any issues as my internal network and DMZ
network aren't out on the public internet, thus no breach in network traffic
security there.

This looks like an emerging issue specific to Win2003 SP1 on Dual-Homed
servers.
We are having same EXACT problem on an IIS box (not Exchange).
