Hyper-V host - slow internet browsing

After setting up Hyper-V on Windows 8 I noticed that when my Domain Controller VM was turned on(hosting AD, DHCP and DNS) my host PC would take a long time to surf the internet.

I did a speed test and, after making the initial connection, saw that my download/upload speeds were normal I realized that it must be because I was hitting the DNS of my "Internal" DNS host on the VM.

Quick fix -
Open your network connections and hit the "alt" button.  Open Advanced - Advanced settings like so:

Then move your External Virtual Switch adapter connection to the top of the priority list like so:

This should restore your host Internet surfing abilities to normal.

Bitlocker recovery key didn't get uploaded to Active Directory

For some reason a laptop did not upload it's encryption key to Active Directory after bitlocker was enabled. I can only assume that it had lost network connectivity somehow.

So I needed to find a way to get the key into Active Directory manually after bitlocker was enabled and most of my google searches were of no help.

This is what I have come up with -
Start with a cmd prompt (ran as an administrator)
Enter the following command: manage-bde -protectors -adbackup C: -id {recoveryGUID}


You might be asking yourself what is the recoveryGUID???
The volume GUID can be found by executing the following:

1. Right click the volume (ex. C: drive) that is bitlocker'ed and choose Manage BitLocker
2. Choose save or print recovery key again
3. Choose save to file
4. We are looking for the "Full recovery key identification".  That is the GUID of the volume that you selected and is also the "id" used with the manage-bde command above.  Make sure you include the brackets with the ID

That should be it, double check in AD to make sure that the information for the recovery key has been populated in the computer object.

Accidentally deleted "All Systems" Collection

*somehow* the All Systems collection had gotten deleted.  I didn't really think anything of it until our HelpDesk system was unable to use it's Asset Inventory function because it was polling the SMS00001 collection.

With some help from Chris Nackers blog I found this vb script which restored the collection with the appropriate collection ID -

'###Begin Code

strSMSServer = "ENTER SERVERNAME HERE" 
strParentCollID = "COLLROOT" 
'This example creates the collection in the collection root. 
'Replace COLLROOT with the CollectionID of an existing collection to make the new collection a child.

strCollectionName = "All Systems" 
strCollectionComment = "This is the All Systems Collection." 
Set objLoc = CreateObject("WbemScripting.SWbemLocator") 
Set objSMS = objloc.ConnectServer(strSMSServer, "root\sms") 
Set Results = objSMS.ExecQuery ("SELECT * From SMS_ProviderLocation WHERE ProviderForLocalSite = true")

For each Loc in Results 
If Loc.ProviderForLocalSite = True Then 
  Set objSMS = objLoc.ConnectServer(Loc.Machine, "root\sms\site_" & Loc.SiteCode) 
End if 
Next

Set newCollection = objSMS.Get("SMS_Collection").SpawnInstance_()

'Create new "All Systems" collection 
newCollection.Name = "All Systems" 
newCollection.OwnedByThisSite = True 
newCollection.Comment = strCollectionComment 
newCollection.CollectionID = "SMS00001" 
path = newCollection.Put_

'Set the Relationship 
Set newCollectionRelation = objSMS.Get("SMS_CollectToSubCollect").SpawnInstance_() 
newCollectionRelation.parentCollectionID = strParentCollID 
newCollectionRelation.subCollectionID = ("SMS00001") 
newCollectionRelation.Put_

'###End Code

Then all I had to do was add my customized query, that removes discovered apple devices, into the collection and do an update/refresh and presto (You could remove the "where" part of the statement to get it back to original) -

select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client
from SMS_R_System
where SMS_R_System.Name not like "%AD"
and  SMS_R_System.Name not like "%AL"
