RID Allocation Value Set at 0, Worried About Running Out of RIDs

Our PDC is the fsmo, and it allocates its own RIDs for SID creation. The issue
is that our RID Value is set to 0, whereas the common default is 500.
Yet, account creation still functions, despite the RID setting. Here
is the reg key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\RID
Values\ ) What is your RID Value set to? My boss has heard about people
running out of RIDs and not being able to create computer and user
accounts because they run out of RIDs. Naturally, we want to avoid
this. When we script account creation we get a pause after the first
account, and then the rest of the accounts are created in a snap. My
boss thinks that the RID issue is linked to the account creation
discrepancy. Any thoughts?

Sincerely,

Hello,

Do not look at that registry value for this information.
From the command prompt of your server type the following

dcdiag /v >> C:\ridcount.txt

this will create a file called ridcount on the root of your c drive.
Open it and lok for RidManager test.
Here you will see the accurate count of RIDS

Dear mdiglio,

  I can't check this until Monday, because I am away from the job. I'll get back to you on Monday. - Any reason why a "0" shows up in the registry RID Value entry?

Many Thanks,

~Angela~

This is not a perfect article for your case but glance over it.
http://support.microsoft.com/kb/316201

"This registry setting is used by the RID operations master to determine what size RID pool to return to a requesting domain controller including RIDS for the local RID pool on the RID FSMO:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\RID Values\ RID Block Size (REG_DWORD)
The system creates this registry key automatically and its initial value is 0. In this state, the internal default of 500 is used."
