It seems you have found out the problems with running an 'open' FTP server. It sounds like you may be running FAT instead of NTFS, which would not be recomended especially for a machine accessible to the outside world.
I would suggest that you set the permissions on the FTP directories and remove anonymous access, or use a different account name for anonymous type logons. Going a step further you could create a virtual directory(use a unique name, 'incoming' or 'upload' are to easily guessed) for uploading files. Its not 100%, but the slight inconvienence would save you from trivial exploits.

I have an anonymous UPLOAD FTP account that I open up to receive these. From time to time I forget and leave this open (I know this is stupid but I thought I could just erase anything that was put there because the small drive would fill up real soon). However, I see someone has hacked into my server and put a bunch of trash that I cannot delete because when I try to delete it, Windows 2K says "cannot find the specified file". I have spent 2 days researching this and cannot find any reference of how to correct this. I did find some reference to looking at the security tab for these files but the security tab is missing! I found some tools which are supposed to set owners for files and they don't work on these files. Here is the log from where the hacker attacked below. Any help would be appreciated. I don't want to have to rebuild my server if possible: #Software: Microsoft Internet Information Services 5.0 #Version: 1.0 #Date: 2002-12-30 06:38:21 #Fields: time c-ip cs-method cs-uri-stem sc-status 06:38:21 80.11.214.63 [1]USER anonymous 331 06:38:21 80.11.214.63 [1]PASS [EMAIL PROTECTED] 230 06:38:24 80.11.214.63 [1]sent /upload/com3+/lpt2+/com3+/d/%15%20%d%D_FCT+/f/.GR+/h/aux+/j/%15%20%+by+Lorg% d%D+/divx/rpc-acb.043 550 06:54:31 80.11.214.63 [1]created rpc-acb.043 226 06:54:32 80.11.214.63 [1]sent /upload/com3+/lpt2+/com3+/d/%15%20%d%D_FCT+/f/.GR+/h/aux+/j/%15%20%+by+Lorg% d%D+/divx/rpc-acb.044 550 07:10:38 80.11.214.63 [1]created rpc-acb.044 226
