A client installed AVG and on one of the installs it had a fatal error. It then broke TCP/IP. I looked into the device manager and for some reason it corrupted the chipset driver and NIC drivers. I got that back installed and I can now ping the loopback address but I can't get anything past that. When I type the IPCONFIG command in cmd all I get is "Windows IP Configuration." I've tried C:\> netsh winsock reset catalog and C:\> netsh int ip reset reset.log but still doesn't work. Any ideas? Could I repair sbs with the install disc? Would that screw even more stuff up?
