A customer of mine has AOL at home and the office. Both sites are running the same account the only difference being the office has two wired PCs and home has one plus a wireless desktop. There's also two laptops which access the account from both locations.

The problem is the wired PC at home keeps logging out saying something about an attempt from another location to log in. All pretty much understandable until you know that the main office wired machine doesn't do it despite running the AOL software just like the home wired one (only these two machines are running the software. The rest don't). You'd think it would do the same but it doesn't. I've told them to unplug the office router when they go home to see if AOL are seeing that logged in but it's apparently made no difference.

The problematic machine is the one which first had AOL on it but I doubt that'll make any odds. I does seem to point towards the office setup being logged in and AOL then not letting the home one in but the office one doesn't log out when you'd think it would or throw up any multiple login errors.

Apparently it didn't happen before the new router was installed at the office. Something is conflicting somewhere but it still happens when the office router is off. I'm reluctant to wipe the problematic one despite it really needed a clean install to be fair.

Both routers have built in ADSL modems. The one at home hasn't changed at all. The one at the office has been configured from scratch so both have the same login details. It's weird that the office one has all the same details but doesn't flip out but the one at home does. The only difference is the make/model of router.

I've thought about multiple users but they need to use the same login at hime and work to pick up any international emails which need sorting there and then.

Any help will be gratefully accepted.

Cheers.
