256986 Description of the Microsoft Windows Registry
SUMMARY
This article describes possible problems that are related to using a Network Appliance file server in a mixed environment with Windows NT Server. This article refers to Internet Information Server (IIS) 4.0 as the affected software that is running on Microsoft Windows NT, but this information can apply to any Win32-based program that connects to a NetApp file server.
MORE INFORMATIONWARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
When a Windows NT-based client computer connects to a NetApp file server, the client may receive the following error message:
Error 1721: Not enough resources are available to complete this operation.
Note that this is what is returned from the client redirector to the Windows-based program. The error message that is displayed by the client may and probably will be different.
This is most likely to occur with Directory Change notifications when connecting to a UNC address. The problem is that the NetApp file server negotiates low LongTermEntries thresholds with the Windows NT-based client; when the client reaches this threshold, the Windows NT redirector returns an error to the Windows-based program, stating that it is unable to post change notifications to the server.
Although this may appear to be a Windows NT issue, the problem is with the file server. When this issue occurs, it looks as if the client software (IIS) is not updating content, but in reality the server
negotiated the limit; the client only enforces this limit by returning an error to the Windows-based program.
A fix for this issue is available to Network Appliance customers. The fix is contained in patch releases 5.3.4R2P1 and 5.3.4R2P2. The fix will be in all subsequent patch releases for 5.3.4 and in subsequent maintenance releases as well. The patch releases are available from the Network Appliance Web site.
As a troubleshooting step and/or workaround, disable ASP and static file caching.
To disable ASP file caching, perform the following steps:
- Open the Internet Service Manager (ISM).
- Right-click the computer name, and then click Properties.
- Click the Edit button to edit the WWW Service Master Properties.
- On the Home Directory tab, click the Configuration button.
- On the Process Options tab, click the Do not cache ASP files option.
- Click Apply, click OK to save your changes, and then restart IIS.
To disable static file caching, you must add the following value to the following registry key:
HKLM\System\CurrentControlSet\Services\Inetinfo\Parameters
DisableMemoryCache For additional information on this setting, click the article number below
