Hello, I have been hacked. The amount of space on my server has been dwindling for the last week. I had 20gb available and I am down to 2gb available space now. I have ruled out spam on my Exchange server. I have just closed all ports to the outside with my firewall. How do I found out where this bad data is that is taking up 17gb of space? I have done a allocation of space on all directories on my C Drive. I have tried unhiding everything. I keep coming up 17gb is lost some where? Any help would be most appreciated, MD

Try JDisk Reporter. It's a free program that shows what files are taking what space on a drive. By the way, it's not a good idea to "unhide" all the files on the system. Windows expects certain files to have the hidden attribute set. It would be better just to enable the viewing of hidden files.

20gig and Exchange? You may not be hacked. Do a search of all files and folders. Sort by date. Sort by size. Perhaps one or both will give you a clue as to where the storage is being used. You may also want to chkdsk /f you drive, look at your restore points, possible backup of the exchange database locally or what installed apps may be doing automatically. You should also look at your firewall logs. Look at event viewer security events. Golly gee wilerkers everyone. Learn to Internet Search

i bet your exchange logs are taking up the space. check those and delete or move as you see fit.

Take a look for the badmail folder and see how large it is. If that's what is hogging up your room, delete the contents.

Wow!! Thanks for all the replies! You are all right! LOL! I must have screwed up on my allocation counting because I found many gb in my badmail and Exchange logs had 14gb. I deleted them and I am all good. The reason I thought I was being hacked is because my dsl lights were always flashing. Even when I wasn't surfing. I know W2003 accesses the internet but I didn't think it accesses it like I was downloading something. I closed off everything with my firewall and they went docile. I had 7gb 2 nights ago and then checked in the morning and had 2gb remaining on my C drive. I will look into my logs on Exchange and see why they took up so much space so fast. Thanks for all your help, Crusader

Its a bit strage to ask maybe but is it save to just delete the exchage logfiles? What if your datebases get corrupted and you need a restore. You need to place them logfiles on a other partition, and when you do a full backup they are deleted themselfs. Lars mcp mcsa\: Messaging mcse -2003
