The type of modification to the invalidateGCConnection attribute and the values specified in the LDAP Modify operation do not matter. The requester must be a member of either the BUILTIN\Administrators group (section 220.127.116.11.12.2) or the BUILTIN\Server Operators group (section 18.104.22.168.12.18).
The following shows an LDIF sample that performs this operation.
dn: changetype: modify add: invalidateGCConnection invalidateGCConnection: 1 -
The effects of invalidateGCConnection are outside the state model. This operation causes the DC to rediscover the GC server that it uses in its implementation of referential integrity (section 22.214.171.124.6).
