Hi all I have an issue with our corporate web server (its a hosted VM, with fasthosts) Basically we only have a 40GB C drive on it, and its been "on the edge" for a while, we ordered more space but they have only been able to add a seperate drive, not extend the C: partition. On friday when i left, it had about 3GB free, this morning, shock/horror, 120MB free!! - would explain why a few support calls cam in over the weekend...! It had restarted after an update at some point over the weekend. looking around to see what suddenly ate the space (still no idea) - i noted 2 things, the windows folder is 21GB - that cant be healthy can it?? and the pagefile is at 8GB, the rest of the space is taken up by program files, inetpub etc, al within reason. this server is purely a web server, it runs IIS7, and SQL server 2008 R2. So my question really is, whats likely to have eaten over 2GB of space all of a sudden? a 21GB windows folder cant be normal surely?? Thanks in advance! - Peter

That sounds reasonable for the windows folder. You mentioned SQL Server. I'd guess this may be the issue. Normally isn't installed on same partition as operating system. Might ask them here about this. http://social.msdn.microsoft.com/Forums/en-US/category/sqlserver http://support.microsoft.com/kb/317375 Also for IIS issues I'd ask them here. http://forums.iis.net/1041.aspx Regards, Dave Patrick ....

On your SQL Server, check the autogrowth settings of the databases if you are limited on space you might want to tweak those. Also check how transaction logs are handled for the SQL Server, they can rack up quite some diskspace as well. For IIS, check what kind of logging levels you have enabled for your web apps and iis in general. If log files are huge you might want to consider changing the setting or regularly moving them to a remote share. Then there is the Windows folder, it's huge and it will only be growing over it's lifetime. Microsoft recommends 40GB of space for Server 2008 (source), but that is excluding all the additional applications you have installed. What will happen over the lifetime of Windows is that the winsxs folder will keep on growing, no real way to stop this.

Hello, 40GB is the recommended size for the Server OS ONLY. If you have the need to install additional applications or server roles then you have to count that ones also to the required disk space or you have to think about relocating this installation to another disk.Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

check where your sql servers tempdb is located, if it wasnt changed, it might be in your program files folder. tempdb is a good candidate for eating up space. http://msdn.microsoft.com/en-us/library/ms345408.aspx has an example how to move tempdb

Thanks for your answers everyone - yes i have been doing a bit more digging. We have had another 80GB partition added, annoyingly now we will have to migrate the inetpub etc across... I'll go through your other suggestions over this week and report back... Thanks again! Peter Wright
