have a server that I was asked to look at. Its windows 2003 standard that runs exchange email. Two partitions on one physical 500gig drive. the c parition was only 12 gig. Exchange and mail store are on D drive. I need to resize c drive so I stop having issues with it running out of disk space since windows uses it for the temp drive unless there are registry keys I can change to make d the temp drive. I only have 60meg on the c drive free which is also why I think MS backup keeps failing to run. What is the best partition resize software to try. I have Acronis Partition 2003 and installed it but I get an error trying to start it up.
