You receive the error “Your computer could not be joined to the domain. You have exceeded the maximum number of computer accounts you are allowed to create in this domain. Contact your system administrator to have this limit reset or increased.” when you try to join a machine on domain.

Tough day?
Cloning and setting up a lot of machines?
And you receive this error:
“Your computer could not be joined to the domain. You have exceeded the maximum number of computer accounts you are allowed to create in this domain. Contact your system administrator to have this limit reset or increased.”

And now? what you have done?

Active directory has a “quota” for how many machines a user can join in domain by day, to change that you are going to need to install the support tools or go the domain controller.

Follow this steps:

  1. Run Adsiedit.msc as an administrator of the domain.
  2. Expand the Domain NC node. This node contains an object that begins with “DC=” and reflects the correct domain name. Right-click this object, and then click Properties.
  3. In the Select which properties to view box, click Both.
  4. In the Select a property to view box, click ms-DS-MachineAccountQuota.
  5. In the Edit Attribute box, type a number. This number represents the number of workstations that you want users to be able to maintain concurrently.

Look in this picture to have a clear idea:

Change Quota Value

Click Set, and then click OK. Like it? Please leave a commen, be nice :)

Process INETINFO.EXE (PID=1748). Topology Discovery failed, error 0×8007077f.

You got the error “Process INETINFO.EXE (PID=1748). Topology Discovery failed, error 0×8007077f. ”
On your event viewer after you changed the IP from your server, and you don´t know what is it.
This error can appear on DSQuery, OWA, OMA and others Exchange 2003 and 2007 Servers.
What this error means?
It means the Exchange Server doesn´t know wich site it is located.
There is a great possibility you don´t include the new subnet on the list of your sites..
So Let´s fix It.

1. Open Active Directory Sites and Services
2. Go to Subnets

Check if your new IP has an subnet there. If not Include it.

3. Include the new subnet (remember class c = 255.255.255.0)

4. Wait 15 minutes or replicate the server manually.

I restart the server just to make sure he gets the new info.

After that your problems should go away :)
Any more questions enter in the forum.

“When you restart a computer that is running Windows Server 2003 or Windows 2000 Server, the computer stops responding, or the “Applying computer settings” screen appears for longer than you expect” Windows Server 2003 hangs with the APC nobreak Software

You install all the patches in the windows 2003 Server, and When you reboot it´s hang on the “applying security policies” or “Applying computer settings” and nothing happens.

In general it lasts for 2 hours, 1 hour for security and another for computer settings, after that you can log on and stop and disable the APC monitor software. In meantime your network connectios will be disabled on the server including the network services.

Why this happen? Check this KB 905716

If this fix your problem, please be nice and leave a comment :)
