Symantec EndPoint MR4 blocks HP Workstations Hard Drives causing BSOD (11.0.4x)

Hey Everyone,

Need a bit of help.

We are having a strange issue were I am setting up device control for removable devices.

I have setup the policy and applied it to my laptop and it works perfectly blocking removabe devices.
When I apply the policy to HP Workstations the machines HDD gets blocked and the PC BSOD. After that I need to go to Safe mode and re apply the old policy.

I used the devtool on CD 2 to look for the device ID and add it into Symantec. The only problem is every PC has a different device ID and we have different models of the HP mainly the xw4400.

I don't really want to exlude the hdd of 30 PCs in our office.

I have one policy that blocks a few applications and also blocks devices.
Disk Drives
Floppy

I have also enabled the rule to only filter removable drives.

Here is an example of what Symantec blocks.

[class name]: <Unknown>
[guid]: {4d36e967-e325-11ce-bfc1-08002be10318}
[device id]: IDE\DISKST380815AS______________________________3.CHF___\52393758584A574D202020202020202020202020

Class ID

Can you try using the class id instead and see whether it makes a difference

Thanks for your all input.

Thanks for your all input.

The problem is if I exclude based on Class ID it will allow all hard drives and even my thumb drive has the same class ID e.g.

{4d36e967-e325-11ce-bfc1-08002be10318}

I need to allow the hard drives on the HP workstations but block USB thumb drives...

I can't block USB either as I need to be able to use bar code readers, and windows mobiles phone with active sync.

Any other ideas?

[can be disabled]: true

I think the main problem might be is with the HP Workstation there hard drives come up with

[can be disabled]: true

When I use dev view and look at the hard drive on my laptop that the policy works on I get this:

[class name]: <Unknown>
[guid]: {4d36e967-e325-11ce-bfc1-08002be10318}
[device id]: IDE\DISKTOSHIBA_MK6025GAS_______________________KA200A__\5&2288DCF3&0&0.0.0
[MFG string]: (Standard disk drives)
[provider]: Microsoft
[driver data]: 7/1/2001
[driver version]: 5.1.2535.0
[hidden device]: false
[Disabled]: false
[PNP device]: true
[can be disabled]: false
[device node]: 0xfcc

Why would a hard drive hosting a operating system come up with that?
