Exchange stops working when I login

August 4, 2010 at 08:37:25
Specs: Windows XP Pro
Our office has 12 computers connected to a SBS2003 server.

Whenever I login or restart my computer, the exchange server shuts down. More accurately, I think the router blocks access to the exchange server so nobody can login to email remotely. When this happens I then reboot the router and it starts working again.

Strangely, this only happens with my computer though. None of the other computers in the office cause Exchange to fail like this.

Any ideas? This is a brand new router and this same problem happened with a temporary router we were using while this one was on order. So I don't this it's a faulty router... perhaps just a setting somewhere.

Using XP Pro, sbs2003, cisco rvs4000 router. My IP address is set to automatic and the server distributes that addresses.

Here's the error message I get from our reporting service (Wormly):
--------------------
Sensor Failure: HTTP
--------------------
Sensor reported error:
error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol


Any thoughts would be helpful.

post a ipconfig /all from your workstation and another for comparison.

One thing I did remember is that I am connected to an additional small 5 port "netgear" network switch (between me and the router), but I don't know why that would make a difference.

I just thought of this. I run a couple of programs that the average user in my office doesn't... like SKYPE and an upload accelerator for an off-site mass storage service we have.

Do you think one of those could be triggering some sort of protection mechanism from the router?

Thanks
