WARNING: 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.

To use this fix, you must add the following registry key to each site server from which Network Discovery runs. This registry change modifies the account credentials under which Network Discovery tries to connect to the clients. The account credentials are changed from using a null account to using Network Abstraction Layer (NAL) to make sure that the account credentials used have appropriate permissions. When using NAL, Network Discovery will first try the SMS site system connection accounts, and then finally the SMS service account. Add the following value and set its data value to 1:

Data value: 1
