Both my sons PC and my PC are having issues after that last windows update.

We keep randomly losing the Mapped local drives from our PC.

The most annoying thing so far is iTunes won't load because it won't connect to the library on the mapped drive.

If we try and click on that driver letter it gives us the dialog box with yadda yadda yadda about letter already in use , not re-mapped error...etc...

I've tried re-mapping and it works for a while...then they drop again...

My PC is wired , his is wireless connection , I've rebooted the modem , the switch box and both PCs.

We have no other issues on the LAN that I can see.
