Correct---multiple sites. Haven't been to them but I presume they are slightly different models, but for the most part all old External models. Have tried reconnecting to all of them since this started, no dice.
-also had the kid from Hypt-pro, (the one said this problem just popped up but has had success with the Trendnet modem) dial into 2 of them the other day to confirm he could connect---and he was successful.
-Have already tried 4 separate modems, including hooking up an external which was a lot of fun. And with all of them I tried using default windows drivers, the latest vendor drivers, the old vendor drivers
-Have tried connecting using Hytermpro, Windows dial up connection, Secure CRT, even putty no dice on any of them.
Like I said, was really throwing up kind of a Hail Mary on this. The only reason I came to the conclusion it might be a Windows problem is because I tried everything I could possibly thing of before deciding it must be software related....adn then I assumed it was the Hypter-Pro. Only after talking to their tech support and finding out they suddenly have similar issues, and trying the next wave of troubleshooting--the stuff I listed above, did I figure it must be windows.
But I can't find anything about new windows problems, which probably isn't shocking given it's 2017 so I'm probably one of like 11 people left who still has to use a modem.
Realistically my next stop is trying to come up with an XP machine and trying that, or maybe a windows 10 box. But that presents other problems because more often than not I have to RDP to the box connected to the Analog line because I use it late at night. ....and I don't think I can get an XP or W10 added to the domain/AD.
should add that there are two analog lines in the server room, and I had someone dial into a modem on them, (and I've done it from a phone), and those seem fine. Also tried a different phone cable. Basically my trouble shooting pattern was to work it back to single points of failure, which led me to the server room where the laptop sits----which is just the line and laptop and now the line is ruled out.
Doesn't help that there are no analog lines anywhere else.
thanks again---as you can see, I'm really reaching. Would have taken 20 pages to list all the stuff I've tried already.
