ID: Q172217
|
The information in this article applies to:
-
Microsoft Internet Information Server version 3.0
SYMPTOMS
If you have more than 1000 WWW virtual directories, you may get the
following error message when an Active Server Page (ASP) is accessed:
Invalid Application Name
CAUSE
You may have supplied a wrong path.
ASP can only support up to 1000 WWW virtual directories.
NOTE: This is hard coded in the ASP code.
RESOLUTION
Microsoft has produced a fix which allows the 1000 virtual
directory upper limit to be changed via a registry entry.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Internet
Information Server version 3.0.
A supported fix is now available, but has not been fully
regression-tested and should be applied only to systems experiencing
this specific problem. Unless you are severely impacted by this
specific problem, Microsoft recommends that you wait for the next
Service Pack that contains this fix. Contact Microsoft Technical
Support for more information.
MORE INFORMATION
The hotfix for ASP now has a new registry entry to ASP that
allows you to change the upper limit that how many WWW virtual
directories ASP can support.
WARNING: Using Registry Editor incorrectly can cause serious,
system-wide problems that may require you to reinstall Microsoft
Windows NT to correct them. Microsoft cannot guarantee that any
problems resulting from the use of Registry Editor can be solved.
Use this tool at your own risk.
To change the upper limit, do the following steps:
- Run Registry Editor (Regedt32.exe).
- Go to the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\ASP\Parameters
- Click Add Value on the Edit menu. Use the following entry:
Value Name: MaxVroots
Data Type: REG_DWORD
Value: a number which is larger than the number of WWW
virtual directories (default 1000).
- Exit the Registry Editor and restart the IIS for the change
to take effect.
