UCIRL,

 

You can increase the interval/timeout but you're probably just masking an issue, and if you did have a problem with the RDP servers further down the line then this course of action may have implications for users been sent to servers that are down but not yet reporting they are down in the BIG-IP configuration because of the high timeout value.

 

Are you able to do a tcpdump to see why the monitors are failing? What about if you changed the monitor to icmp for a test, do they stay up then? If so then this would point to tcp connections on the server being the issue.

 

Hope this helps,
