Never happened on DC20 ? When this happens, does a reboot resolve the issue?
What has been the frequency? any chance you run a daily DCDIAG report? What does your replication health look like on a daily basis?

This seems to have been precipitated by adding a Read Only Domain Controller and adding a number of Linux samba servers. The symptoms of the issue follows: On DC11 (2008 sp2 ReadWrite DC, 2GB ram, virtual machine on ESXi 5.0u2): 0.) cpu usage is low, typically under 5%. Memory is 800M cached. 118M free. 1.) In the Directory Service event log the following two errors are logged: *Event ID 1168 - Internal error: An Active Directory Domain Services error has occured. Additional data: Error value (decimal): 1450, Error Value (hex): 5aa, Internal ID: 124048b *Event ID 1168 - Internal error: An Active Directory Domain Services error has occured. Additional data: Error value (decimal): 1450, Error Value (hex): 5aa, Internal ID: 1240627 2.) This has happened three times on DC11, and once on DC10 (also 2008 sp2). The time that it affected both DC11 and DC10, manually pushing passwords-to-be-cached to the RODC failed. 3.) Trying to read the properties of an object with ADSI edit (connected to DC11) returns: Windows could not load the values for all the attributes. Operation failed. Error Code: 0x2121. The search failed to retrieve attributes from the database. 00002121: SvcErr: DSID-0312048E, problem 5012 (DIR_ERROR), data 1450. 4.) Attempting to run Windows Update gives Error 0x800705AA, which I believe is ERROR_NO_SYSTEM_RESOURCE. 5.) Running 'runas /user:me cmd' fails with "5: Access is denied" 6.) The server appears to continue to service auth requests, and LDAP binds still work. However, we seem to encounter intermittent issues with the samba servers during this time. Site topology: CORP: DC4, DC5 (server 2003, auto-site coverage disabled by registry) DC10, DC11 (server 2008 sp2) CAL: connected to CORP RODC1 (server 2008 R2, read only domain controller) NY: connected to CORP and DRSITE NYDC4 (server 2003) DRSITE: connected to CORP and NY DC3 (server 2003) DC20 (server 2008 R2) DC4 is the Schema Master. All other roles are on DC5. repadmin /showrepl and dcdiag don't show any errors. Two additional bits of information. (1) For some reasons, IIS is installed on the DC10 and DC11 domain controllers. (2) a similar thing recently happened with our Exchange 2010 server (2008 R2). The same error with 'runas' failing occured, IIS app pools couldn't restart, and the windows process activation service couldn't be restarted (also with error 5 access denied). I am planning on setting up a new RWDC, physically in CORP but in the CAL AD site, and seeing if the issue follows the new server or stays with DC11. Any help would be appreciated.
