I am having an issue with tcpsvcs.exe using excessive cpu cycles (99%). I thought it might be Norton AV so removed same with no luck. I think it might have started when I set up a printer on tcpip using a Linksys printserver but not sure. I can remove it using task manager and it doesn't seem to cause any problems when I do so. Any thoughts or suggestions. I talked with MS and they couldn't seem to find any useful info. Thanks for your help, jodower
