Hi Guys,

I am currently trying to work through an issue for a client and i am starting to lose the plot and would like some external input on further things i can try.

Background on the situation is

I deal with a client who has an office based in Albany who predominantly use VPN from sattellite offices (normally home offices) to connect in and work on Documents / sync email (they have SBS2003).

the week ending 19th of August a client called to say that the VPN was unusable and outlook would just lock up and not sync any emails and it was just unsuable, she had her home line connection tested and it was deemed to be OK.

On monday i recieved a call from another Partner who was experiencing the same issues from a different location.

I also was having trouble using VPN using RDP onto the server to be able to get into the router or even just work on the server. we started to eliminate options and decided to replace the Thomson gateway that was supplied with a new Cisco Small Business router, this was configured and put in place which we hoped would resolve the issue, This did not solve the issue and so we looked at getting telecom involved to run some checks on the line etc. this came up with no fault and everything was working OK according the the Chorus tech but we were still having issues.

I then changed the point of where the VPN was connecting from the server to then create a connection from a workstation in the office and got a colleague to test with the same results.

On friday i called and logged a fault with telecom again and explained the situation to the tech i was talking to, he organised a port reset to see if this would resolve the issue which it hasn't from talking to the affected staff this morning..

and i am just wanting to get some feedback on what you guys think could be at play here. before i ring telecom again.

Hi to start with I would configure the clients and server to allow Outlook Anywhere. Then you don't need a VPN to run Outlook.

where is the vpn terminating? Is it on the SBS box or on the router itself?

the VPN passes through the router and is terminating on the server itself, using PPTP

I would suggest you find a way to take the SBS server out of the loop for testing purposes so it can be ruled out as the source of the problem. Are you able to terminate it on your Cisco router at all or is putting in a seperate RRAS server for testing a possibility?

Also, is OWA setup on the server? If so how well is that working from an external connection?

we did try terminating it to just a client workstation to take the server out as the main point of connection and it still gave us the same issues, and if we create a local VPN connection the connection works fine so i don't believe it is routing and remote access on the server. when testing OWA it seems to work without any issues from the testing we have been doing.

ok, to me it sounds like you are on the right track re it being a telecoms fault. Do you have a 3g router that you could chuck in to do some testing to help prove that? It might still be slow but should be faster then what you are describing.

Only other thing that I guess you have checked is that GRE is allowed?

Thanks for the response, with GRE we have checked and confirmed so thats not the issue, with the 3G router that is something i hadn't thought about and will have to look into.

Its just so fustrating as we are just chasing our tails

well i have just got off the phone with Second Tier support, and it looks like even though they had requested a plan change (from 20gb) upto 40gb after they hit the cap last month, it was never actioned fully and the throttling was still in place yet only he could see the system that told him that and 1st tier would not of known that.

so there has been a request in to lift the throttling and i will have to wait and see if this resolves it... i am sure as hell hoping

Throttling strikes again, I have seen this with one of our Nelson remote workers before. Forgot all about it!
