Server 2008 R2 - RDP Issue - Sometimes drops then will freeze on re-connect

Hi all,

I installed Windows Server 2008 R2 about a month ago on to my new HP Proliant Microserver, all is well apart from a bug I have found with RDP, as this is my preferred method of remote access I use this a lot.

It works ok up to a point, I find that if I start a session, do what I need to do and log out, it works ok, I can re-connect then no problems when I want to, however if I log on, and leave it un-attended for a short space of time (anywhere from 5 minutes up) I will get disconnected, then when I try to re-connect I get prompted for the password, it goes to connect, I get the Windows loading screen in the background and it will freeze. I can't get on then unless I manually re-boot the server.

Has anyone else experienced this at all? (I use this over the WAN/LAN, its not my PPP dropping or packets dropping, as I have been monitoring my WAN connection and its not dropped its link or packets from either side of the connection, what ever this issue is it seems to be server bound).

Bump as this is doing my head in now, I have to keep rebooting the server as I loose RDP session to it, going to have a dig around on google later

I notice it happens more if I RDP in to the server then minimize the window for a bit

^ Perhaps.

I have tried this, although I am not confident this will fix the issue. But given it a go anyhow, it only does it on my server at home, so I am not sure Bitmap caching on my RDP client will make a difference.

Incorrect MTU causing fragmented packets, or a device or application doing port forwarding somewhere between client & server and not handling fragmented or large packets properly.

RDP does not like fragmentation.

My netgear routing is doing the port forwarding although I am pretty sure this has not just happened over a WAN connection but also when im RDP on to the server on the LAN.
