We have a client that is connecting to our office via home network (VPN - Microsoft RRAS - 2003 Std SP2).  Sometimes the client gets connected just fine.  More often than not though, the VPN connects, registers, hands off IP, subnet, DNS, etc., but nothing works.  Can't ping via name, IP, nothing.  It seems that the connection is sending packets just fine, but not receiving any responses.  Here's the home office setup:

Home Office:
3 Windows XP Pro SP2 workstations
Connected via Linksys Gigabit switch (24 port) to
D-Link DIR-655 Router - SIP Firewall, ALG Config available (PPTP and IPSEC - turned on and off no change)
Comcast 6MB cable internet

HQ:
Windows 2003 SP2 Std. Edition running RRAS
Other clients connecting and working just fine.  
Cisco PIX 505

1) I would check the MTU settings, as well as update the router firmware, and check for malware also or programs that could interfere with VPN.

I hope this helps !

Have you run packet filtering on both sides, meaning on the workstation and on the server while trying to connect? Is anyone else establishing another PPTP connection at the same time as this user at the same location?

It seems to be a router specific issue.  All of the other PC's at this location are experiencing the same issue.  I did check the MTU size, and both the router and PC's are set to 1500.  Yes there are others connecting via PPTP at the same time, but not from the same location.  Because this is for an exec, we have decided to negate the MS RRAS, and go with a hardware (PIX to PIX) VPN solution.  Thanks for your help and suggestions guys.  I will request a Mod to refund the points, as that is the appropriate thing to do in this case.  Again, thanks for your help anyhow!!!
