Did you have TLS1.0 turned on?
In a default Windows NT 5.x installation, TLS has to be turned on manually. It’s in the Internet Options control panel, under Advanced. This is where you also turn off SSL2/SSL3.
In this day and age, you would be limited to 128-bit ARC4, or 112-bit (nominally 168-bit) Triple-DES.
XP cypher isn’t a high enough level (I need 256b for some of our vcenter clusters and other management platforms and there is no fix for XP or the browsers... it’s just done unfortunately. I suppose one could try to downgrade the web and ssh daemons to accept the lower cypher levels, but it got to be too much of a fight and I just moved on to win7 which I’m getting along with pretty well. I just couldn’t deal with v8.x and the interface. im stuck dealing with 2012 server more and more every day now and I hate it just as bad if not more.
