Having a strange issue with RDP to an XP machine through a L2L tunnel.
Tunnel is between an ASA5505 and ASA5510. Site A 5510, Site B 5505
I have a handful of Win7 and XP Dev machines running on ESXi 4.1 within Site A.
Site B to Site A
Site A to Site B
AnyConnect
I have tried to Telnet on 3389 to the XP VMs with no success.
Any ideas?

Hello,
Have you check the MTU on the regular RDP using the IPsec tunnel? Fragmentation are known issues when using RDP across IPsec

Hello Cybervex3,
This sounds like a fragmentation issue.
Can you do the following on Site A:
crypto ipsec df-bit clear-df outside
Then try to connect, if this does not work change the MTU size manually on the client to a value of 1300
Let us know the result,
Regards,

Ran the command on Site A ASA
Set the MTU on the XP VM and the Machine I am trying to RDP from to 1300. No changes
