CRS: Access Violations Occur If Route Is Over 300 Characters

ID: Q167727

The information in this article applies to:

Microsoft Commercial Internet System version 1.0 - Microsoft Content Replication System

SYMPTOMS

An access violation in the Content Replication System (CRS) may occur when a route contains more than 300 characters.

The following example demonstrates the behavior:

1. Create a route with 31 destinations. Make the machine names at

   least 10 characters long so that more than 300 total characters
   are included in the route.

2. Create a project that uses the route created in step 1.

3. Start the project.

4. An access violation occurs in CRS when the project starts.

CAUSE

CRS uses a hard-coded maximum route size of 300 characters.

RESOLUTION

Crsdll.dll was modified to allow creation of routes with more than 300 characters, however the CRS interface cannot be used to add servers for large routes due to limits of the interface.

To add servers for large routes, you must edit the registry manually using the following steps.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall 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.

1. Start Registry Editor (Regedt32.exe).

2. Go to the following key in the registry:

   HKEY_LOCAL_MACHINE\Software\Microsoft\CRS\Routes

3. Locate the key that describes the route that you need to edit.

   The route may be similar to the following:

   HKEY_LOCAL_MACHINE\Software\Microsoft\CRS\Routes\My Route

4. Edit the Value Destinations:REG_MULTI_SZ:.

5. Enter the additional server names in the Multi-String Editor, pressing

   ENTER after you add each name.

6. When you have added all the server names, click OK.

7. Exit Registry Editor.
