Exchange 2003 need more disk space on Drive C

Running Exchange 2003 on Server 2003 Standard.  I am running out of disk space on Drive C: I hae approx 600mb out of 12gb remaining.  Here's my question:
1.  What log files can I delete: ebt.log,res1.log, or exxxxx09.log (ex-date.log files)?
2.  Under c:\windows\ there are a great number of $NTUninstalKBxxxxxxx$ folders...I know these are the uninstall folders for each security patch or security update, etc.   Is it safe to delete these?
3.  Or lastly, any suggestion as to how I can create more disk space on C:
Thanks in advance for your assistance.

Do you have full backups running? These backups should be set to purge the logs every time.

"Folders that have uninstall as part of the name (for example
$NtUninstallKB282010$ which reside in C:\windows (hidden folders) are Window
Hot Fix Update folders/files) can be safely deleted (providing you never wish
to uninstall the updates). I would recommend leaving these folders for a
period of at least a month to make sure the update is working correctly.

How to remove Exchange Server transaction log files
http://support.microsoft.com/kb/240145

"You may occasionally have to manually remove transaction log files if you have run out of hard disk space. Or, you may occasionally have to manually remove transaction log files if you anticipate running out of hard disk space before you can run a full or incremental online backup of all the databases in a particular storage group. If you remove a log that contains data that has not yet been written to the database files, the databases will no longer be mountable after an abnormal stop. Therefore, you must determine which logs are safe to remove before you manually remove any Exchange Server transaction log files."

"If you are concerned with disk size on a multi-user computer for example, a public computer where thousands of users can log on, you can also use the Group Policy setting that removes cached versions of the profile on logoff. The policy is called Delete cached copies of roaming profiles, and it is accessed under the Computer Configuration\Administrative Templates\System\User Profiles node of the Group Policy snap-in."

If you can add another array/drive to your server, you can move the Exchange stores to the larger drive:

just keep in mind that if you have rather large stores, this move can take a while during an outage window!

Lastly, [but most importantly!] please ensure you have a good working backup of the server and of the Exchange stores before deleting files! Best to move the files first, and test; then when you are comfortable remove the files as per MS best practices.

Many thanks for the speedy reply and options...I plan on doing server maintenance over the next few days.  I will report back to you how it went.  Thanks again.  I'd like to keep this "ticket" open until I do all the stuff above....if that's ok with you.

The log files that you mention should be purged after an exchange aware backup f the infrmation store.

There is no point in doing differential backups if the store since it performs a full backup because the file will always change so you may as well perform a FULL backup not a COPY this way your logs will get flushed.

How big is the EDB and STM files? Is there another volume you can move them to?if so follow this guide: http://www.petri.co.il/move_exchange_stores_to_a_different_disk.htm

if that's not an option look at how much whitespace is in yur database, look for event ID 1221 in the event log (there will be 2 at around the same time every day) howich free space do you have?  If it's a lot you may want to consider an offline defrag.  Make a copy of the EDB + STM files (just in case something goes wrong) then run:  ESEUTIL /d "full_path_to_edb_file.edb" the store needs to be dusmounted for this to work.
