Unless you have intervened by setting TSL manually, the answer depends on how 
your AD was installed/upgraded. In 2K it was 60 days. In 2003 SP1 and beyond, 
default TSL is intended to be 180 days but a bug in R2 didn't increase it. That 
was first rectified in SP2 IIRC.

It's best to just check the attribute "tombstoneLifetime" on the object 
"CN=Directory Service,CN=Windows 
NT,CN=Services,CN=Configuration,DC=<domain>,DC=<tld>

It will be either <not set> which = 60 or 180 unless it was manually set. 

If it isn't at 180 most people I know set it there because "that's what it's 
supposed to be now" and it increases-

* The useful life of backups that are used for data recovery scenarios. 
* The useful life of system state backups that are used for promotions using 
the Install from Media feature. 
* The time that domain controllers can be offline. In your case the  "in the 
crate time" :-) 
* The time that a domain controller may be offline and still return to the 
domain successfully. 
* The time that a domain controller may experience a replication failure and 
still return to the domain successfully. 
* The number of days that the originating domain controller retains knowledge 
of deleted objects.

Subject: DC Offline

I know we have discussed this before, but I probably didn't pay attention and 
now I need to know.
How long can a DC remain offline before it goes sour? I have a need to build a 
small network then ship it off somewhere. It may end up staying in the crate 
for a few days as well, so let's say it could be off for a week.
It would be a standalone domain and this would be the only DC for it.
Its demo stuff....
