I have eventually found the issue... Someone at some point had installed GFI endpoint security, and blocked all USB devices, and then removed it from the server without uninstalling the end points. The way I got around this was to go on to all the affected PC's and do the following... Boot from Windows CD Choose REPAIR (R) and select the option to open ...

There is a wealth of public information on how the DC Locator process works. Essentially it performs a series of DNS lookups and LDAP pings, and also attempts to stratify the results by selecting the closest domain controller. It's unusual for Windows DC Locator to continue to use a failed domain controller, unless the domain controller is passing the ...

There is no immediate impact if your PDC DC goes down. You can plan to manually seize the PDC role from one of the remaining domain controllers. The process is descrbed well here https://www.petri.com/seizing_fsmo_roles

Instructions below are for how to authenticate to a Samba server using Kerberos from a Windows 7 client. I have not tested for other version of client and server: On the Windows 7 client, "Run As Administrator" cmd.exe. Then enter this command to supply Windows with knowledge of the Kerberos domain controller (KDC) for the kerberos REALM.COM: ksetup ...

This is fairly fundamental. Remove DC from domain using the normal procedure. DC becomes a member server in the domain. Remove member server from domain. Create new domain using the normal procedure. Job done. I'd personally be considerably happier if "re-image server" was included as a middle step to ensure that any info/cruft on the server didn't ...

Converting my comments/thoughts into an answer. It appears that you have given all of the students: Administrative control over all the computers. Anonymity by allowing them to all share the same admin account. This is probably a suboptimal configuration in a typical classroom setting. Although you claim that the students are not administrators on the ...

You need to add an entry for SERVER01 pointing to the server ip address in the local pc's hosts file as below: 192.168.168.168 SERVER01 In windows: %systemroot%\system32\drivers\etc\hosts, which in most cases is: c:\Windows\System32\drivers\etc\hosts. In linux it is: /etc/hosts

Assuming that you mean they're moving their website from one website host to another website host then change the DNS record(s) related to the website ONLY. You don't need to make any other changes in DNS. Do not make changes to their MX records, NS records or any other records not related to the website.

First, you can short circuit DNS by entering the IP and domain into your hosts file locally. 1.2.3.4 example.com example.com Two, you can address the new host by IP address, then FTP/SSH in to set it up. Three, email is controlled by DNS MX records. Just ensure they're unchanged when you change the domain A records and you'll be fine. If you have no MX ...

When you disable a computer in Active Directory, you're basically disabling the computer account. I suspect that the computer is passing authentication requests to a domain controller other than the one you disabled it on, and that information hasn't replicated yet. It's also possible that you have some kind of larger replication problem in Active ...

Dealing with the WHOIS protocol is quite messy. At least for human digestion it's typically most practical to use a client that has been pre-configured in such a way that it can present a mostly consistent interface to the user. Doing so means having a very extensive configuration with not only information about which servers to use for particular queries ...

It's not clear that this is possible with the CLI whois tool. However, some WHOIS web-based services will do this for you: https://whois.domaintools.com/google.com
