Hi, searching hi & low, regarding intermittent disconnects for RDP sessions.
Am interested in any pointers.
Situation is following: Multiple RDP servers behind ASA, sometimes a user, and sometimes all users to one server from outside our ASA suffer intermittent disconnects (once a day, once a week, couple times a day etc). We have never noticed this when connected for many hours within the internal network. So I rule out servers, NICs and Switches, and try to concentrate fault finding to the ASA as a common bottleneck. Inbound connection is fibre, full duplex, no packet loss according to our national ISP, so we have no known issues with this connectivity.
ASA config is pretty much straightforward, allowing RDP through to dedicated servers. Haven't touched timeout, nor inspect.
What would YOU test or look for first in fault finding this? What should I look for in the syslogs? Could the timeouts spook us, or MTU, or random PAT conflicts - or no way that it's the ASA that is the trouble ???
