You may experience one or more of the following symptoms on a computer that is running Microsoft Windows Small Business Server 2003:
The computer frequently runs out of disk space.
Internet mail flow stops.
Microsoft Internet Information Services (IIS)-hosted sites stop working, and that includes the http://companyweb site and the Microsoft Outlook Web Access (OWA) site.
The information store mailboxes are dismounted after the reserve log files are filled.
Note The reserve log files (Res1.log and Res2.log) are Jet database format files that are used by the Windows Internet Name Service (WINS). These log files function as emergency placeholders if the system runs out of disk space. If there is not enough disk space to create a transaction log file, the server flushes any outstanding transactions into these log files. The WINS service then shuts down and logs an event to Event Viewer.
Incoming faxes stop working.
Users cannot save files to network shares.
Report generation fails.
Various snap-ins do not open.
This problem may occur if a computer that is running Windows Small Business Server 2003 does not have much disk space available. The low-disk-space scenario may occur if you enable the Remove E-Mail Attachments option when you run the Configure E-mail and Internet Connection Wizard, and many attachments are subsequently removed from e-mail.
Note When you run the Configure E-mail and Internet Connection Wizard, you can specify that the e-mail attachments that you receive from the Internet are removed. You can also specify a folder where the removed e-mail attachments are then saved.
To specify a folder for removed e-mail attachments, follow these steps:
Run the Configure E-mail and Internet Connection Wizard.
In the Remove E-Mail Attachments dialog box, click to select the Save removed e-mail attachments in a folder check box.
Type the path of the folder in the Folder Location box.
To resolve this problem, you must address the low-disk-space problem. Verify that the folder that contains the removed e-mail attachments does not use too much disk space. (When you run the Configure E-mail and Internet Connection Wizard, you can specify a folder where removed e-mail attachments will be saved. When you designate a folder, all removed e-mail attachments will be saved to the folder. If no folder is designated, the blocked e-mail attachments are removed and discarded without being saved).
To determine the folder size, right-click the folder in Windows Explorer, and then click Properties. If the low-disk-space problem is caused by too many attachments in this folder, remove the attachment files to restore the disk space, and then investigate the source of the attachment files.
To prevent this problem, you can use disk quotas to limit the disk space that is allocated to the folder that contains removed e-mail attachments.
