Global Catalog to service the logon request, and if the only DC is not a GC, the users may be unable to logon. To workaround this issue, you may try one of the following methods: Method 1.

On the General tab, click to select the Global catalog check box to assign the role of global catalog to this server. 5. Restart the domain controller. Note: Allow sufficient time for the account and the schema information to replicate to the new global catalog server before you remove the old GC. Method 2. Disable the requirement that a global catalog server be available to validate user logons ======================= To eliminate the need for a Global Catalog server at a site and avoid potential denial of user logon requests, use the following

2007 by Greg — No Comments ↓ Event ID 40960 and 40961 "The Security System detected an attempted downgrade attack for server…" In my case, when we logged the user in and opened Windows Explorer to a network share, we received an error. "The system detected a possible attempt to compromise security." Then in the event logs, we saw the errors above. Turned out, a previous administrator saved a logon password under this user account. To remedy, you must open Control Panel, User Accounts, and then the Advanced tab. Then click the Manage Passwords button. In there, you can set and modify network passwords for specific servers. (a feature I never knew existed!) Sure enough, the server we were connecting to was in that list and set to the name of an ex-admin.
