David Gardiner's questions

I'd like to enable the new Domain Keys DKIM email authentication feature for a domain hosted in Google Apps.

Some of my users use an external SMTP gateway (such that when they send email, it doesn't go through smtp.gmail.com).

I have an SPF record configured for the domain, and this allows the external SMTP gateways as valid SMTP hosts. (I realise SPF is different to DKIM)

Will enabling DKIM adversely affect the external gateway email? eg. Are the externally sent emails at risk of being marked as spam because they would not have the DKIM signature, or will DKIM only positively benefit emails sent through Google's SMTP server?

I have a Windows 7 VM running on a Hyper-V server. I connect to this VM from another machine (also running Win7).

Will my remote connection be able to benefit from the new RemoteFX features coming in in the next service pack for Win7/Server2008R2, or is this only for terminal service-type configurations?

Using Hyper-V, what are the pros/cons of using the "Physical Hard Disk" option when adding a drive to a VM as opposed to just creating a fixed-size VHD that is as large as the disk?

The intention is for this disk to be allocated to a single VM so there isn't any requirement to have anything else using it.

On Windows Server 2008 R2, trying to start a VM named 'TFS' in Hyper-V Manager displays the following message:

Hyper-V Manager

An error occurred while attempting to start the selected virtual machine(s).

'TFS' could not initialize.

Failed to create partition: Insufficient system resources exist to complete the requested service. (0x800705AA)

'TFS' could not initialize. (Virtual machine ID 252EAC02-59DB-4BE5-BB9A-296B5BA4BC78)

Recently (eg. in the last week or two), when I RDP to one of our servers running Windows Serve 2003 64bit, the login screen is black.

If you can guess what it is prompting, then you can still login, and once you get past the login screen the desktop displays correctly.

Any suggestions as to what would have caused the login part to be blank?
