TS2003 disconnect every 7-9 minutes

[Guest Dana]

Bear with me as I'm not a tech gal (I'm an accountant with some tech

experience)...

 

We have a TS2003 server that we use relatively infrequently. There are

about 6 users who use it to access our Netware server. Rarely at the same

time. 3 of the users it seems work fine. The other 3 seem to get messages

while they're working that they're disconnected. This disconnect seems to

come up every 7-9 minutes. They reconnect and they're right back where they

were but for only another 7-9 minutes. We use a WatchGuard MuVPN. Any

ideas? Is this a VPN issue or a WTS issue or both?

 

Thx,

D

May we assume they are coming in over the vpn? Are the users on a dsl

line? Many times issues like this are related to MTU size discrepancies.

Hi Jeff,

Yes, it's thru the VPN & yes those users are on DSL. I'm really not

familiar with MTU so can you help or point me in the right direction?

Thx again,

D

MTU (Maximum Transmission Unit) refers to the maximum packet size allowed by

a particular network segment. The effective MTU of a connection is the

minimum MTU among all the segments on the connection. In your case, the DSL

+ VPN combo is leading to a much smaller MTU than Ethernet supports.

 

You want your MTU as high as possible without fragmenting or dropping

packets; when VPN is in the mix, this value can vary quite substantially.

 

See http://support.microsoft.com/default.aspx?scid=kb;en-us;q314825 for

information on how to configure the MTU used by a particular machine. It's

mostly trial and error, so it may take some time to work out the optimal

setting.
