RPC Locator needed for PPTP-VPN for reliable UNC resource access?

I use a WinXPSP2 remote host to connect to my home office via a PPTP-VPN
connection to a Win2003SP2 RRAS server that is behind my firewall. Both the
server and remote host use a virtual WAN adapter, configured via the RRAS
service, instead of separate physical adapters.

Occasionally, once the connection is established, I cannot reliably access
network resources via a UNC path (\\server\share). I receive a network path
error. However, if I terminal in to the target server (also by name, not IP)
via mstsc.exe (RDP 5.2), I can connect just fine.

Must the RPC Locator service be running on the remote host to ensure UNC
access reliability?

Re: RPC Locator needed for PPTP-VPN for reliable UNC resource acce

Thank you.

I have NetBIOS over TCP/IP disabled on all network adapters already. The
problem is intermittent anyway...any further thoughts?
