We have a SBS 2008 server which is has an incorrectly formatted 46 GB C drive.
We are at a stage where we have moved all SQL / Exchange / Sharepoint / WSUS databases / transaction logs to the D drive along with everything else which can be moved away from C.
Right now, on C are only the program files for SBS's integrated applications and the Windows installation. There is a WINSXS folder in the windows directory which takes 22GB. We are aware that we cannot touch that so need some advice on how to make room for Windows to run properly. Right now, we have crippled exchange to make it work in <1% free space environment and are expecting some sort of corruption any day now.
Does anyone either know a good way of reducing the size of the winsxs folder or safely expanding the size of the C drive?
