When searching for my issue, I came across this thread
. The OP's problem initially sounded a lot like mine, but ended up being different enough that I still need help.
I'm using Computer A to remote desktop to Computer B. This has worked fine for a few years now, up until the other night. Suddenly remote desktop connection no longer works. I don't know what I downloaded, updated, or whatever in the last few days that changed anything. I will say that ever since I've had Computer A (2+ years), I've left the firewall off. Suddenly, tonight I found it was on, though once I discovered that I immediately turned it off. All the testing below was done with the firewall turned off (I'm also assuming that the fact that safe mode didn't help removes the chance that it could be a firewall).
I tried remote desktop connection from Computer C to Computer B and Computer D, which worked fine. Thus, the issue seems to be with Computer A (remote desktop from A to D also doesn't work). A to B is the main problem I'm trying to fix.
Things I've checked:
-- Both A and B allow remote desktop connections
-- Both A and B have network connections
-- pinging B from A does not work.
-- A does not have a firewall up and running
-- I checked netstat -a (or -an, -aon, -ano, etc.) on Computer A, did not see any hint of 3389 at all
-- Tried running Computer A in safe mode with networking, still nothing (no ping, no netstat connection, etc.)
-- Terminal Services in Computer A seems to be working fine, according to services.msc
-- Checked Event Viewer for anything related to remote desktop. I didn't see anything, but it is possible I missed something (it's late, didn't check thoroughly).
I would appreciate any and all help! I'll have access to Computer B during the day, and Computer A during the evenings (starting ~6 p.m. EST). Will try to answer any questions. Thank you in advance!
