Dear all,
I have a small RDFARM collection of 2 RDS servers which have started to Blue Screen Crash on me every few weeks. The servers are virtual, running on Hyper-V. OS is Windows Server 2012 R2 for both Hyper-V and Guests. The physical Hyper-V server has not crashed at all. Other Guests, not running RDS, have not crashed. Only the RDS servers have crashed, example:

Server1 The computer has rebooted from a bugcheck.
The bugcheck was: 0x0000003b (0x00000000c0000005, 0xfffff802e1c5e532, 0xffffd00023594e60, 0x0000000000000000).
A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 083017-18890-01.

Server2 The computer has rebooted from a bugcheck.
The bugcheck was: 0x0000003b (0x00000000c0000005, 0xfffff801aee64522, 0xffffd00174c26e60, 0x0000000000000000).
A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 072717-64765-01.
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000003b (0x00000000c0000005, 0xfffff80111dea522, 0xffffd00027405e60, 0x0000000000000000).
A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 072617-14234-01.
The computer has rebooted from a bugcheck. The bugcheck was: 0x00000018 (0x0000000000000000, 0xffffe334585aea88, 0x0000000000000020, 0xffffe334585aea70).

A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 072517-15609-01.

The physical server is an HP Proliant DL380 G9. Any help would be appreciated.

Now that issues are resolved.

Generally now a days the issue is third party drivers that were forced in.
RDS Servers sometimes have weird issues because of this.

First thing I'd do is get the debugging tools and check the memory dumps and see if they tell you anything.

If that doesn't tickle your fancy.
I'd take a copy of an RDS Server and run it as local admin and run the system file checker on the copy and see if it says anything
Link

I say the copy because sometimes things can go funny.
As you mentioned its probably the RDS Servers themselves rather than the host.

You didn't mention the OS involved. My bad...

These are the various links I use when I need to refresh on debugging
I'd do all this work on a VM that you don't mind potentially looseing.

Yes, in my experience Win08R2 is stable enough on itself and i only seee BSOD's when there are driver issues like smartcard software, nicdrivers, storage drivers, etc. Ive seen quite a few on Win16 S2D lately due to driver issues, for example;
- intel P3600 driver install (officially not for Win16, just Win12R2)
- mellanox driver install on a Dell OEM card instead of native mellanox
- Dell storage S130 driver with RAID1 volume (icm with S2D)

Debugging will help you find the files (like .dll/.sys) that are the cause and this will give you a clue on which software is the cause.  If you can't find clues in the debugging, you can also strip the installed software piece by piece to see if the bsod's stop if you have removed once of the pieces. If yiou try that approach, it's better to start with a clean server and install software piece by piece. To prevent the bsod's still occur due to a not removed driver.
