My setup is as follows
1 Server 2003 set up as a DC
1 Server 2003 configured with RRAS
The RRAS server is configured with a Static IP. (configured on my DSL modem) Both servers are on a 10.x.x.x subnet. I have a second network 192.168.x.x. that is getting IP's from the DSL modem (2Wire HG 2701) Qwest is my ISP. I can use RDP to connect to the RRAS server from the other PC's I have (the XP PC's all have a 192.168.x.x address). When I try to connect to the RRAS server via a Citrix session from work it makes the initial connection then I get the following error:
Your Remote Desktop Session has ended.
The connection to the Remote computer was lost, possibly due to network connectivity problems. Try connecting to the remote computer again. If the problem continues, contact your network administrator or technical support. I am thinking that there is something awry on my end in that it makes the initial connection but then it drops. If it were on my work end I would not think I would be able to establish a connection at all. The only thing that is new in this equation is that Qwest sent me a modem upgrade because I upgraded to the 7MBps circuit. Any thoughts would be appreciated.

seems to be an MTU Size problem.
When you´ve got direct acces to the internet, run SG TCP/IP Analyzer!
- try reducing generaly the MTU for the connecting computer to e.g. 1300 for all adapters 1st, you can switch back later and identify the Adapter which has to be reduced.
Eventualy it´s an ICMP Problem, where someone is blocking ICMP Messages like "Packet to large" or "Dont Fragment"
