I have a Windows Server 2003 R2 with SP 2 which was infected with viruses. After removal of viruses, several system functions are not working properly. I am unable to browse to the network, connect to this server from other servers and workstations, open Windows Firewall, open Network Connections, or install certain programs. It also disabled several services that I have since enabled manually, but am still unable to do many functions. Can I just reinstall SP2 to correct these errors? I tried the reset TCP/IP by using NetShell and also the rundll32 setupapi... netrass.inf commands without success. Thanks.
