hi guys

Got exchange 2007. The C drive is basically completely full up now and we can't do anything.

I have also two other drives; one with 200GB free and another with 150gb free.
Our transaction logs is on the C drive.

I tried moving the database logs for our 'Third Storage' group to one of the bigger disks. But as it was doing so, the amount of space on our C drive was reducing drastically so I cancelled it.

This is the method I tried using: http://exchangeshare.wordpress.com/2008/05/22/move-committed-exchange-transaction-logs/

Please can someone help me to do this as I'm utterly stuck?!

Thanks
Yashy

I'm on server 2008. Trying to work out how to do this NTFS symbolic link.

Martin, I'm a little confused and evidently a little rattled by this as getting frantic phonecalls:(.

So i have the C drive with the transaction logs. I have an E drive which is where I'd like the transaction logs to go to.

Would you be able to show me how to do this with a few steps? The makelink is not working as I'm probably doing it incorrectly.

Doing junctions or symlinks is totally nonstandard and asking for trouble down the road IMHO. If you can move the pagefile off the C drive to another drive and do the reboot I would do that. Medium term neither your Exchange log files nor databases should be on the C drive. You need to move them using the Exchange Manager. A regular backup will truncate your log files. If you temporarily switch to circular logging your log files will take less space, but you also won't be able to use them for recovery and is only a very temporary solution until you get things moved.
Some programs did have problems with Junctions, but simlinks should be closer to the Linux soft links in functionality and should be okay to use.

It is quite easy to make a link.

First start up a Command Prompt, but run as Administrator.
To do that, go to Start->All Programs->Accessories and right click on the "Command Prompt" icon and select "Run as Administrator"

In the command prompt, first make the directory that you want to link to with the command:
mkdir  e:\myfolder

Next make the link with the command
mklink  /D  c:\mylink  e:\myfolder

Now any file created in C:\mylink will actually be in e:\myfolder.
By the way, kevinhsieh is probably right that you would be better off doing it properly - it's just that a symbolic link would be a quick and dirty - but nonstandard - fix which could get you back up and running quickly.

You will need to stiop the Exchange services for a while whatever you decide to try though.  You won't be able to copy or move the log files if they are in use.

Guys, I ended up doing a Symantec Backup Exec FULL backup of the entire information store and the C drive (where the logs were). When it completed, freed up around 40GB of space so it took us through to the clear.
