What is your DFS queue size? If that isn't replicating properly you could be hitting your DFS queue max instead of a page file max.

So I'm investigating hard drive space issues on all of our servers and I noticed on every single inherited DC (whether it has a good amount of free space or not) the page file is exactly this down to the MB:
That seemed huge to me so I checked the VM's I spun up (Windows Server 2012 R2) and they are:
DC1
DC2
why such a huge disparity?
This is one of the reasons I often check, and anything before Server 2012, I manually set the paging file size to be 1.5x the amount of RAM or 4GB max... Unless you have several thousand user accounts, a DC shouldn't need that much swap space.
So the OS is misjudging the amount of virtual memory required?
Do you have a reason to believe that?

It's a Windows Domain Controller... What could cause it to even need a 25GB paging file?

If a DC is paging, you have big issues.

Seems to be replicating properly. Nothing is queued currently.

Yeah but why is it paging? There is such a low % of memory being used and the page file is big.

The size of the page file doesn't matter. Have you checked the page in / page out rate?

Look for pages/sec and page faults/sec

Oh... I hope nobody needed that.

@DustinB3403 Uhm, clean that up with no downtime? You'd need to replace all the cables, or at least be able to unplug things for a couple minutes while you reroute the cord through proper cable management of some sort. Good luck with that.
