During login to domain X, where X is the domain passed into NPLogonNotify as lpAuthentInfo->LogonDomainName or the string 'LOCALHOST' if lpAuthentInfo->LogonDomainName equals the name of the computer, the following keys will be looked up.

1. NP key. ("HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider")

2. Domains key. (NP key\"Domain")

3. Specific domain key. (Domains key\X)

If the specific domain key does not exist, then the domains key will be ignored. All the configuration information in this case will come from the NP key.

If the specific domain key exists, then for each of the values metioned in (2), they will be looked up in the specific domain key, domains key and the NP key successively until the value is found. The first instance of the value found this way will be the effective for the login session. If no such instance can be found, the default will be used. To re-iterate, a value in a more specific key supercedes a value in a less specific key. The exceptions to this rule are stated below.
