I was working with CW 345 this morning and thier DSL went down yesterday. they DSL techs did some “things” and then finally fixed the DSL. after the DSL tech got off the phone the back machine would no longer connect to the front machine. I dailed in and found that they had disabled netbios over TCP/IP which is name lookup with TCP/IP. since we map by name ws-1 VS 192.168.1.100 it wouldnt work . Could ping could browse by number just not by name re-enabled the switch worked fine.
the switch is located under LOCAL AREA CONNECTION>TCP/IP>ADVANCED(under TCP/IP)>WINS> should be checked to enable LMHOSTS lookup and default.
They switched it to disable netbios over TCP/IP.
