Windows Updates
(OP)
Windows updates tried installing last night and this morning the computer was stuck on installing 3 of 3. We powered it down, when it came back up everything seemed to be fine except catia can't find our license server. Those that didn't install the updates are working fine. Any ideas as to what got changed and what we need to do? We checked the firewall and that seems to be the same as it was and we tried restoring the system but it failed for some reason.
Thanks,

RE: Windows Updates
...following Microsoft Update broke the TLS connection for license usage by increasing the key length on the Windows machine to 1024 and the server is only supporting 512.
KB3061518
The fix right now is to update the registry as MS recommends in the articles below
Click Start, click Run, type regedit in the Open box, and then click OK.
Locate and then click the following subkey in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\Diffie-Hellman
On the Edit menu, point to New, and then click DWORD Value.
Type ClientMinKeyBitLength for the name of the DWORD, and then press Enter.
Right-click ClientMinKeyBitLength, and then click Modify.
In the Value data box, type 00000200, and then click OK.
Exit Registry Editor, and then restart the computer.

RE: Windows Updates
Are you using LUM or DSLS?
What CATIA level are you using?

RE: Windows Updates
If you don't have the Diffie-Hellman key, I would just simply create it under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms
Then add "ClientMinKeyBitLength" set to 0x00000200(512) as Microsoft suggests.

We are on R2014. We will update our license server this weekend and see if it fixes the issue and allows clients to use a 1024 byte key.
