SSDP Service Failure Mystery

My network uses a cable model, a linksys 4 port router and a Linksys Wireless Access Point. WindowsXP and Linux machines and a ReplayTV use the network.

One of the XP boxes cannot get outside. I can ping the router and the other machines and I can use Windows shares to move files between the machines. I can even ping outside (i.e. google.com) but only by address (i.e., DNS isn't working). Also, DHCP doesn't work so I need to set up a static IP address.

This box works fine if I boot Linux on it so I have ruled out a HW problem.

What happens is the SSDP service fails to start. It uses 99% of the CPU and prety much disables the machine until I kill the SRVHOST process that is trying to launch it and disable the SSDP service.
Any ideas? Thanks.

Start by disabling your unniversal plug&play service. That is what is probably pegging your cpu while looking for SSDP connections. For your setup you don't really need it.

See if that alone takes care of your dns/dhcp problem. Set your pc back to obtain an ip automatically and dns info automatically. Under advanced options make sure that dhcp is enabled.

Reboot and try it again.

Thanks, drbob. The UPnP service is disabled but the problem is still there.

After poking around a little it looks like one of MS's security patches might be causing someof your problems. Here's a link to a discussion regarding other users that have had similar issues after applying this patch: http://snurl.com/pcn

The only resolution seems to be to set a static ip (like you have already done). But since you are doing that, to get your dns issue taken care of you will need to set your dns information for the connection manually also.

I found the solution posted in the MS Knowledge base. Apparently, removing McAfee Personal Firewall using the Control Panel breaks the network in a way that can only be fixed by re-installing the McAfee product. Unfortunatly, I never owned the product so the root cause is still a mystery. I must have removed some other unrelated software that had the same effect.

I fixed the problem by installing a borrowed copy of McAfee Personal Firewall, then removing it using the McFee Uninstall instead of the Control Panel (as MS suggested).

Thanks for all your help.
