- Microsoft Internet Information Services 5.1
SYMPTOMS
When you open the properties for the Web Site folder in Internet Information Services (IIS) 5.1, you may receive the following error message and specific metabase property values may change unexpectedly when you try to move from the Cache Options tab in the Application Configuration dialog box to any other tab in that dialog box:
CAUSE
When you configure a custom script error message that is more than 259 characters long, several additional metabase fields may be overwritten, depending on the length of the string that is entered.
WORKAROUND
To work around this problem, make sure that the character length in the ASPscriptErrorMessage property is always less than or equal to 259 characters. If the value exceeds this limit, additional metabase properties are overwritten, and the data in the additional metabase properties is lost even if you later reduce the string length that is stored in the ASPscriptErrorMessage property.
After the metabase properties have been overwritten, Microsoft recommends that you restore your metabase from an earlier metabase backup to recover.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows XP Service Pack 2.
MORE INFORMATION
The metabase property that is associated with this field is named ASPscriptErrorMessage. You can set the value of the ASPscriptErrorMessage property by using IIS Manager or by using any metabase editing tool. To use IIS Manager to update the value, follow these steps:
- Open IIS Manager.
- Right-click the Web Sites folder, and then click Properties.
- In the Web Sites Properties dialog box, click the Home Directory tab.
- Click Configuration.
- In the Application Configuration dialog box, click the Debugging tab.
- Set Script Error Messages to Send text error message to client.
Note that if you type more than 259 characters in the text box, additional metabase property values are overwritten.
The properties that may be overwritten with incorrect data include:
- Cache ISAPI applications
- Write unsuccessful client requests to event log
- Enable debug exception catching
- CGI script timeout
- Do not cache ASP files
- Limit ASP files cached to
- Disk cache directory
The following are the known values you may see set for specific metabase properties as the Script Error Message value increases in character length:
- At 260 characters, the Cache ISAPI applications check box is cleared.
- At 262 characters, the Write unsuccessful client requests to event log check box is cleared.
- At 264 characters, the Enable debug exception catching check box is cleared.
- At 266 characters, the CGI script timeout value is modified.
- At 269 characters, the Do not cache ASP files option is enabled on the Cache Options tab. Additionally, the Limit ASP files cached to value changes to 1000.
- At 285 characters and higher, characters are appended to the Disk cache directory field. Because this field must contain a valid directory path and the appended characters make the path invalid, the error message that is mentioned in the Symptoms section is generated when you try to save this new value to the metabase file.
Note that these are cumulative symptoms. In other words, a message of 262 characters disables both Cache ISAPI Applications and Write unsuccessful client requests to event log.
