Intermittant Remote Desktop Problems.

[iCEhOT]

Hiya,

I'm having trouble connecting to my home computer via remote desktop, and it's a very strange problem I'm having - I have a router with TCP port 3389 forwarded to my home computer correctly. Also have the Windows XP SP2 firewall turned on, for my lan connection, with remote desktop allowed through as an exception. Also have firewall logging turned on and cant find any dropped packets in the log.

I can connect and stay connected for long periods of time, however when trying to display large amounts of graphical data over the remote desktop connection the connection seems to drop. For example if i'm browsing a website remotely, and one with mostly graphical images (rather than text) causes a pause then a disconnection. This also happens when trying to browse photos or anything else like that. This can happen straight away if i've left my home computer displaying an image like that when trying to connect to it - or i can stay connected for hours on end and then look at something like that before being disconnected.

The strange thing being, that these things dont make any difference to anything when using the computer locally, all graphics work fine, the network works at very fast speeds internally, and there doesnt seem to be a problem connecting to the internet and browsing webpages locally either - infact if it wasnt for the remote desktop problems I would say my computer works perfectly.

I have tried and tried to find the cause of this, the firewall logs simply state the connection as being closed, and nothing more. I have looked over many websites for remote desktop problems, and can't find anything explaining this issue. Could someone please help me??

Ok i have managed to use another computer connected directly to the computer in question (hence eliminating both the router and internet connection). The problem still occurs using the LAN, and with or without windows firewall.

I'm not all that familiar with Remote Desktop, but it sounds to me as if maybe the network just can't handle all of the traffic involved in loading massive amounts of data across the remote connection.

Do you get the same problem if you are trying to pull up graphic-intensive content from the local machine, or is it only when pulling stuff off the net? Also, are you getting any kind of error message from the remote PC when the connection is dropped?

Hi mate,

Not sure if I can help you, but you mentioned you used another computer connected directly to the "computer in question" and you still experienced the problem...

What if you were to work vice versa.... So you take your "computer in question" and use that one to connect to the other computer. If you do the same actions you did previously, does the connection still drop?

I use RD alot and never experience any problems.

Good luck...

BTW... have you tried using a modified TCPIP.SYS?

Yep, get the same problem with any graphics, although sometimes it wont connect at all, and takes several times.

Haven't tried the other way round, could try that, but my next port of call is to plug in another network card and see if it's the onboard network causing problems.

What Screen Settings and LAN setting have you chosen on the RDP profile?

[iCEhOT]

Mostly use the broadband profile, have changed to all the different profiles etc, and the display settings, doesnt seem to make much difference to it all...
