Hi Mike, thanks for the response. I've been doing some digging around myself and think I may be onto a solution (in theory anyway - putting it into practise may be a different matter!) How does this sound? I set up a GRE tunnel between the remote site and 7206 router at head office, which in...

In our set-up we have a central site with a large number of remote sites connected. We have moved a number of remote sites from ISDN connections to ADSL connections. However, we would like to keep the ISDN and use it for backup. The problem I have is - how do I implement ISDN backup with our...

Folks, ignore my last message - problem now resolved! It looks like what was required was an uninstall of the Cisco VPN client software AND a reset of the TCP/IP stack. However, it had to be carried out in the correct order. 1) Uninstall VPN client software 2) Reset TCP/IP stack 3) Reinstall...

Folks, thanks for all the helpful advice so far. Looks like we've made a breakthrough, of sorts. Tried a few things, resetting the TCP/IP stack, uninstalling some pieces of software. Nothing had any effect until... We uninstalled the Cisco VPN client software on this machine and - wow - it...

Hi, that was also a step I had considered myself. Only thing I was wary of - is there any potential repercussions from resetting the IP stack? i.e. is it possible that I could screw things up even further rather than fix things!? Thanks for all the assistance so far!

Yeah, we already looked at the TCP/IP filtering - it wasn't even enabled though. Even tried enabling it and having everything as "permit all" but that made no difference either! Its really got me scratching my head!

Hi, thanks for the response. The failure is occuring at the machine itself - pathping doesn't really reveal anything as it just times out. I'm talking about pinging it from the same LAN - even down to both devices being on the same switch so its no even going through any routers or anything. I...

Hi, thanks for the response. No, I don't believe it is a router blocking ICMP requests - if it was then I would have expected to see the same behaviour for other devices on the same subnet. I also would have expected to see pings FROM the "problem" machine being blocked. I have also tried...

I was troubleshooting an issue a user had with their telnet sessions dropping when they left them idle, despite there being no timeouts configured on the servers. The user is running Windows XP SP2. I captured the network traffic for the user's network segment and found that, at the time of...

I've never actually used this software but a colleague at a previous company I worked for used to swear by it and it sounds like it could be the kind of thing you are looking for. Its called Q Check - you can check it out here...

I was asked to troubleshoot a problem a user was having with their sessions dropping out to the server (using Reflections software) I was informed that there were no idle timeouts configured on the server or anything. I checked the network switch port the user was connected to and there were...
