OK I think we are on to something here with Kims Idea!
I was headed to something similar as what Kim posted but had not thought of the MAC address issue.
Kim below is my template for what I call the TCP/NETBIOS/Winsock enema!
Going a little deeper! And gets a little log info.
Code:
netsh interface ip delete arpcache
ipconfig /flushdns
ipconfig /release *
ipconfig /renew *
ipconfig /registerdns
nbtstat -RR
netsh winsock show catalog >"%USERPROFILE%"\Desktop\lsp.txt
netsh winsock reset catalog
netsh winsock show catalog >>"%USERPROFILE%"\Desktop\lsp.txt
netsh int ip reset >"%USERPROFILE%"\Desktop\tcpreset.txt
Reboot see new icons on desktop, paste contents of lsp and tcp.txt back to thread.
