I have an odd problem on my notebook (HP Pavilion dv7). My Internet connection seems OK for the most part. But lately I've been having trouble with Remote Desktop connections. While I can connect to remote computers, the connection is very flaky, and usually drops after a few seconds. Sometimes it'll successfully reconnect automatically, and sometimes not. But even after successful reconnection, it'll just drop again after a few seconds.

This appears to be independent of which RDP host I'm connecting to, and which network I'm connected to locally, whether wireless or wired.

Other remote control apps like TeamViewer and Ammyy seem to work fine.

Any ideas?

Try a continuous ping to like ping 8.8.8.8 -t and see how many packets are dropped or time outs you get. –  Dave Rook Dec 18 '12 at 12:22

@Shaul @DaveRook also adding some load to continuous ping might be a good idea. ping -l 1000 8.8.8.8 -t Also open wireshark, filter RDP protocol and check if you receive some RST or FIN packets –  mnmnc Dec 18 '12 at 12:24
    
@DaveRook - just started a ping as described to the remote host, during that time I set up a RDP connection, which dropped after about 5 sec. All this time, not one ping packet lost. –  Shaul Dec 18 '12 at 12:28
    
@mnmnc - ping - see comment above –  Shaul Dec 18 '12 at 12:29

@Shaul Check the MTU on your network card and MTU on switch router - maybe there is a difference and some packets are dropped. Try adjusting the quality of RDP connection in the settings. Check if only RDP is affected - possibly watching Youtube videos have the same problem with crashing video buffer? –  mnmnc Dec 19 '12 at 8:21

This sound like an administrative problem the fact that VNC protocol seems the to be working (teamviewer and ammyy are VNC clients) fine. Which would indicate that it is either a User are RDP setting on the server. If your company use's an Active Directory get them to check the session limit under the sessions tab(If it's windows of course), also if this is happening to more that one user it, get the administrator to check the RDP Session Host Configuration for the override setting.

Hi Sam, thanks for your answer. Please note that this problem is independent of the RDP host. Also please read comments on the question, indicating that since installing & running Wireshark, the problem seems to have stopped for the time being. –  Shaul Dec 18 '12 at 14:53
