I have a machine that is having intermittent problems resolving names both internally and externally. Even using WINS and an LMHOSTS file it is taking up to two to three minutes to resolve a server name. It has the same problem resolving Internet names. Local names are caching properly, the WINS server shows up correctly as does the DNS server in WINIPCFG. Any solutions short of rebuilding the machine from scratch?? The network card does not appear to be the problem as mapped drives come up without a problem as well as pinging by IP address.
