RWW and TERMINAL SERVICES access suddenly drops. Comes back on router reboot?? Help!!

Hi This is really strange.

I am running SBS2003, and also a seperate terminal services server.
The router is a netgear DG834v2.

There are several users around the world accessing the remote applcation, and other users accessing their PCs via the RWW service on SBS2003.

It's been up and running fine for over a year, but now this week a strange thing has started happening.

Out of the blue, and usually when our UK office is closed it isn't possible to access the remote application. At the same time access to the RWW webpage stops too- the page won't load on a browser.

I get called out in the middle of the night and find that all I have to do is reboot the router.

So I thought the router was faulty and somehow losing its port forwarding settings so I configured a new router and set it up. Everything was working fine until again in the night exactly the same thing happened.
I can't see any logs in sbs2003 saying there is anything wrong.

Does anyone have any ideas? Many thanks. I need a night's sleep!!!

Hi, when this happens though you have no issues connecting to the router remotely to restart it  ?

Hi Johan

No I can't connect remotely to the router firstly as I didn't have remote access to the router enabled for security reasons, secondly I can't remote into any PCs on the network to access the router from the LAN because the issue means that RWW is not accessible.
I get the welcome to xxxdomain page, but when I click on rmeote web workplace the page won't load.

OK that makes sense, there is an idle setting on your router and I am wondering if its dropping the ADSL connection at night because its idle. I would say for sure its not an SBS or TS issue, especially if a router restart solves this.

Hi Johan its one idea, but wouldn't explain how I can access the welcome page of the server.
Think you're right, it seems like it can't be a server issue, but it's done the same thing on two different routers. Within the LAN everything is working perfectly. Really very weird..

I'm wondering if its a cached page, have you ever refreshed your browser? also before you restart the router it would be worth pinging a host on the internet from the LAN to confirm the connection is down, if thats the case, like 8.8.8.8 .

Can you get a RADIUS log from the ISP because it will show if your ADSL is actually disconnecting.

Hi, I would be interested to see what is happening at night on the connection. Obviously something is causing this, can you think of anything that happens at night that might effect the connection? Obviously you would start by ensuring that the router had the latest firmware however if you was one of my customers I would pull the Netgear and replace it with a Vigor 2820, then install Kiwi Syslog on a Windows PC and start logging it. The only reason I say a Vigor is because they are widely used, I know for sure in the UK. I have hundreds of ADSL connections and have good experience with these devices. Im not saying that there is anything wrong with the Netgear though and I am not suggesting this as a solution but for me it would represent something that I know to be solid and allows for logging because right now I would be looking to eliminate my own equipment because although I have no experience with your setup it sounds to me like an ADSL problem. Do you have any other devices between the Netgear and the LAN like another firewall or an ISA server ?

Hi Johan

Thanks for your help. In the end I didn't find out what caused this, it sorted itself out.
But I think it was the ISP. They had been upgrading the service around this time and could have caused the problem. Wish we had a definate answer to help others out but there you go.
