There might be different reasons but one of them is that the clocks between a workstation is a DC are not syncronised. I believe Windows allow not more than 1 minute difference

This is something that needs to be fixed / changed on the site's server, not your computer. There is nothing wrong with your computer; there is something wrong with the site you are visiting.

The bridgehead server is a domain controller that has been either administratively assigned or automatically chosen to replicate changes collected from other domain controllers in the site to bridgehead servers in other sites.

The domain controller is only of one type but it can have different roles

Domain Naming master

RID master

PDC

Schema Master

Infrastructure master

Schema master (forest wide):

The Schema Master controls all updates to the Schema within the forest.

Domain Naming Master (forest wide):

The Domain Naming Master role is responsible for the creation and deletion of domains in the forest.

PDC Emulator (domain wide):

The PDC emulator role provides backwards compatability for Windows NT backup domain controllers (BDCs), the PDC emulator advertises itself as the primary domain controller for the domain. It also acts as the domain master browser and maintains the latest password for all users within the domain.

Infrastructure Master (domain wide):

The Infrastructure Manager role is responsible for updating references from objects within its domain with objects in other domains.

RID Master (domain wide):

The RID Master manages the Security Identifier (SID) for every object within the

No a user defined in active directory cannot access a shared drive if they are not part of the domain. You will need to set them up as a user on your computer.

Active Directory replication uses compressed and encrypted traffic to reduce the impact on corporate WAN links. This helps in minimizing bandwidth usage and ensuring efficient communication between domain controllers.

The global catalog server.

Nslookup ,dnscmd.exe

After running DCPROMO, A text file containing the appropriate DNS resource records for the domain controller is created. The file called Netlogon.dns is created in the %systemroot%\System32\config folder and contains all the records needed to register the resource records of the domain controller.

Netlogon.dns is used by the Windows 2000 NetLogon service and to support Active Directory for non-Windows 2000 DNS servers.

If you are using a DNS server that supports the SRV resource record but does not support dynamic updates (such as a UNIX-based DNS server or a Windows NT Server 4.0 DNS server), you can import the records in Netlogon.dns into the appropriate primary zone file to manually configure the primary zone on that server to support Active Directory.

so if you are using w2k with dynamic update it will automatically create the SRV

The global catalog contains a complete replica of all objects in Active Directory for its Host domain, and contains a partial replica of all objects in Active Directory for every other domain in the forest. The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory forest. The global catalog is stored on domain controllers that have been designated as global catalog servers and is distributed through multimaster replication. Searches that are directed to the global catalog are faster because they do not involve referrals to different domain controllers. In addition to configuration and schema directory partition replicas, every domain controller in a Windows 2000 Server or Windows Server 2003 forest stores a full, writable replica of a single domain directory partition. Therefore, a domain controller can locate only the objects in its domain. Locating an object in a different domain would require the user or application to provide the domain of the requested object. The global catalog provides the ability to locate objects from any domain without having to know the domain name. A global catalog server is a domain controller that, in addition to its full, writable domain directory partition replica, also stores a partial, read-only replica of all other domain directory partitions in the forest. The additional domain directory partitions are partial because only a limited set of attributes is included for each object. By including only the attributes that are most used for searching, every object in every domain in even the largest forest can be represented in the database of a single global catalog server.
