You cannot access a Web Distributed Authoring and Versioning (WebDAV) Web folder from a Microsoft Windows  client computer. When you try to do this, you may experience the following symptoms:

• When you use a Universal Naming Convention (UNC) path to access the Web folder, you receive an error message that is similar to the following:
  
  \\server\webfolder\folder is not accessible. You might not have permission to use this network resource.
  
  Contact the administrator of this server to find out if you have access permissions.
  
  A device attached to the system is not functioning.
  
  error 31 = ERROR_GEN_FAILURE

• When you map a driver letter to access the Web folder, you receive an error message that is similar to the following:
  
  Disk is not formatted
  
  Windows cannot read from this disk. The disk might be corrupted, or it could be using a format that is not compatible with Windows.

• When you try to enumerate the Web folder at a command prompt, you receive the following error message:
  
  File Not Found

To work around this problem, add a DWORD entry that is named FileAttributesLimitInBytes to the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\

Configure the FileAttributesLimitInBytes registry value to the size that you want, and then restart the WebClient service.

To do this, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
   
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\

3. On the Edit menu, point to New, and then click DWORD Value.
4. Type FileAttributesLimitInBytes for the name of the DWORD, and then press ENTER.
5. Right-click FileAttributesLimitInBytes, and then click Modify.
6. In the Value data box, type the value that you want to use, and then click OK. For example, if the Web folder contains 20,000 files, type 20000000 in the Value data box.
   
   Note If the default value is 1,000,000 (1 MB), Windows XP will enumerate a maximum of approximately 1,000 files in one folder. The actual maximum number of files may vary, depending on the number of file attributes or file properties. By default, the WebClient service does not ask for specific WebDAV properties. Therefore, the server returns all file attributes. The Microsoft Office integrated Webfolders redirector does ask for specific WebDAV properties.
   
   
7. Exit Registry Editor.
8. Stop and then restart the WebClient service. To do this, follow these steps:

1. Click Start, click Run, type cmd, and then click OK.
   
   
2. Type the following commands, and then press ENTER after each command:
   
   net stop webclient
   
   net start webclient
