mstsc /span not working on windows 8.1

Posted on 2014-02-26

I've always used mstsc /span to remote into my computer at work when off site, then use splitview at work cpu to give me the true multiple monitor experience remotely.

However, this morning, as normal, I do mstsc /span, and the session only goes over one monitor.  I checked the span box across all monitors, unchecked it, rechecked it, did mstsc /multimon, all to no avail.

I did install a bunch of updates last night, so not sure if that broke it or not.

Please start troubleshooting by using another computer and see whether it allows spanning/multimon. Could be broken at the target computer, not the client.

sorry for the delay
It is not the computer connecting to, as I have tried to connect to 3 ohter computers with the /span attribute and it doesnt' work.

And on other computers the client still works as expected?

Ok. Try sfc / scannow
of not successful, try an inplace upgrade using your setup DVD.

sfc scan did not fix it.  I'll be rebuilding this PC soon anyway, so I'll just drop this issue for now, thanks

Try the inplace-upgrade first, it won't hurt.
