Have an issue I hope someone can help us with . .
Last year we setup a dedicated terminal server for a client to allow several remote users to work from home on the custom apps our client uses.
Everything has been working perfectly until this week when for some reason the system stops accepting connections (and in some instances disconnects users already connected) between 4-4:30 PM everyday without fail. Strangely enough, the system works perfectly the next morning and stops at 4-4:30 again. We can still rdp onto it on the local LAN without issue but when we try to connect from an external IP address we get the "configuring remote session" and then it just comes up with the "Unable to connect to remote computer" error message.
So far we've tried/tested:
Doing a local reboot.
Rebooting and checking all router details - the router reports the connection been sent to the terminal server correctly.
Fully updating server 2k3, office, NOD32, etc.
Licencing is fine - 5 user licences, only 4 people actually use the machine/have access.
Nothing obvious in the event viewer.
Changed the network switch over/changed port/rebooted network switch.
The system is an old workstation we installed server 2003 onto (clean install). The only other programs installed are ESET NOD32 Anti-Virus, Office 2007, and one of the custom apps the clients uses (a basic access database utility). The system has been running fine for 6+ months.
We're scratching our heads trying to work out what could be causing it but are coming up fruitless. Any ideas?
Thanks in advance.
