Win svr 2008 r2 ent - user can not log into remote desktop after installing march's 2015 important updates

Question

we installed march's 2015 important updates onto all of our servers.  three of our servers are not allowing RDP.  
these servers have windows server 2008 r2 enterprise sp1  installed.  
we enter in the username and password in the rdp dialog box and click on ok.  the rdp dialog box comes back for us to enter in the username and password.  
we do have kb3046049 and kb3002657 installed.  
is there a v2 of kb 3002657 for windows server 2008 r2 enterprise?  
on one of the servers
1. I disabled rdp
2. stop and start the following services 
remote desktop configuration
remote desktop services
remote desktop services usermode port redirector 
remote procedure call
3. enabled rdp
4. added the users allowed to rdp into  server
This allowed us to RDP into that box with the username and password.  
But the other two servers the steps performed above did not work.  
Any solutions for Win Svr 2008 R2  enter sp1?

It is related to the SSL cert revocation and Microsoft is very lame these days and gets the code on MU but can't sync up the KB.
