RDP & VPN's

[Beau]

In our remote offices we are experiencing disconnect problems and some lag
issues as well with our W2K TS. I was told by a guy (salesman) that
installing a Linux VPN solution would help allievate this problem. I am not
so sure about VPN's, but I'm thinking that adding the VPN overhead will
acutally slow down the connection between offices. Anybody have experience
with this? Will a VPN help?

Remote offices all using DSL 512/256
HQ uses DSL 784/256

I'm thinking that we need to get a faster DSL connection...any other
opinions?

I concur. A VPN will just add overhead. TS is encrypted to begin with, so
you don't need it to be in an VPN.

Your DSL is also plenty fast for TS. I'd start to took in other places for
the lag.

Lag can be a cause from lots of things.
Answer a few questions and I'll try to help

1) How many Remote sites are you connecting through your home office DSL?
2) How many Total computers are at the Remote Site/s Using TS.
3) How many computers per site are using TS probably would paint a better
picture.
3) Are you using your home office DSL for more than just TS?


VPN will encrypt all network data from point A to point B (this will cause
some overhead). If you aren't using a VPN, then the only thing that is
encrypted is TS traffic! You might want to ask yourself is that enough?
That's the only thing a VPN will do for you. Just let you tunnel traffic.
If you have someone telling you it will speed things up, fire him/her.

Here is our senario:

HOME OFFICE
T1 to INTERNET
(Internet Access, Email Server, 4 Hosted Websites, TS VPN for Remote
office & Remote VPN for Home Users)


(VPN'S)
4 Remote sites connected DSL 386k/128k with 2-6 PC's per site using TS
6 Remote sites connected DSL 768k/256k with 5-10 PC's per site using TS

(Point to Point)
4 Remote Sites connected via Office to Office ISDN (128k) with 2-4 Pc' per
site Using TS(converting to DSL)
2 Remote Sites Connected T1 with 10-25 Pc's Per site Using TS


We have roughly 30 remote sites that are connected point to point T1's.
The terminal server is working so well,
I'm thinking about buying DSL for all our sites with only < 15 users on them
and going through our VPN. If I did this, I'm going to up
our T1 to 2 T1's

I usually estimate that each active pc consumes about 50k-64k of bandwidth
(MS says 25-40, but i have found that 1 64k isdn line with 2 users is
usable, but a little choppy)

Answers to questions:
1. We have 5 remote sites.
2. About 2/5 machines conecting to TS at each site. With probably no more
than 20 connecting at one time.

We also have about 10-15 users locally that use the TS as well.

I've also run Performance Montior on the Server here's what I have:
(Averaged for entire workday from 7-5) Samples taken every minute.
Physical Disk - % Disk Time = 14%
Memory - Pages/Sec = 20.05
Processor - % Processor Time = 12%
Active Sessions = 12
Total Sessions = 21

Thoughts?
