Problems with MEAP
Automatic retrieval of domain information and service information retrieval fail when Windows Server firewall is set.
DNS server* communication is blocked by the firewall.
Stop blocking the default port 53.
* A DNS server usually performs communication with the UDP protocol using port 53, but the data may be processed with the TCP protocol if it exceeds a certain size.
User authentication fails when Windows Server firewall is set.
Communication using LDAP server authentication is blocked by the firewall.
Stop blocking port 389.
* Communication is performed with the TCP protocol using port 389 by default. If you have changed the port, stop blocking the new port.
Cannot log in to Active Directory.
Did you perform user registration before installing Active Directory?
After installation, accounts are automatically generated in the "Users" folder, but since a user logon name is not set, you cannot log in to the Active Directory of User Authentication because the user information cannot be retrieved even if a key is generated. Perform the following operations to change the settings.
|
1
|
Start the "Active Directory Users and Computers." management tool of Active Directory.
|
|
2
|
Right-click the user registered before installing Active Directory.

Startup is slow.
A host that name resolution cannot be performed for (an address that cannot be identified) is set in the SRV record retrieved with automatic domain retrieval.
The DNS server set in the machine is not found or cannot communicate. Check the settings and communication environment.
If a standby time for network connections is set on the machine, change the setting.
Login is slow.
Check whether the domain name specified in the DNS server that is set can perform name resolution (or whether the address can be identified), and make changes if necessary.
The DNS server set in the machine is not found or cannot communicate. Check the settings and communication environment.
Multiple domain controllers manage the specified domain. Login may be slow because User Authentication performs the authentication process for all domain controllers until login succeeds. Check the domain controller and make changes if necessary.
