Remote connection broken

[Guest]

Hi,

I'm trying to connect to a remote server using remote desktop on a wireless
8.11g connection from a Toshiba laptop w/1200x800 resolution. When my laptop
connects (or seems to), I get the dropdown at the top of the page but
otherwise the screen is black for 20-30 seconds until I get a 'connection to
the remote computer was broken' error.

I've tried changing display resolutions on the laptop and changing color
depth in remote desktop, doesn't help. I'm able to connect properly using an
old Dell using the same wireless router (Netgear WGR614 with latest firmware)
so the router doesn't seem to be the cause either. My MTU is set to 1500.

Any ideas would be greatly appreciated ! I need to connect to work and
would prefer to use the Toshiba but can't. I've searched the MS site for
troubleshooting tips but haven't been able to find anything that helps.
(Unfortunately, the laptop didn't ship with an OS disk so I can't try a
repair and don't want to reinstalled and erase everything.)

Thanks.

try to low MTU. That may be the problem. This link may help,

Many thanks!

For others who may have the same problem, here's more detail:

Using Bob's suggestion, I tested my traffic stats:

1) Opened a command prompt
2) Ran 'ping -l xxxx -f yy.yy.yy lowering the #s in xxx until I was getting
no packet loss

where:

xxxx = MTU packet size (see below) and
yy.yy.yy = ip address of the site I needed to connect to

For my site, I got errors until I dropped the MTU size to 1300.

3) Since I'm connecting over a VPN connection, I then used Dr. TCP to change
the MTU size for my VPN adapters to 1300.

And that did the trick!

Thanks again, saved me a lot of time.
