Find the GPO name with an GUID?

LDAP? That guid is an attribute on an object in Active Directory, so yes you can query for it:

(&(objectCategory=groupPolicyContainer)(name={D45A4D0F-77BE-4116-9F5B-CF96E81D2DDC}))  

You can also search for that value in the Group Policy Management Console:

You can use PowerShell's Get-GPO cmdlet for this. It contains a -GUID switch, which is what you want to use here. You also need to have the AD Commandline Tools from RSAT installed so that you have access to the Group Policy module. If you use the AD module, you have this installed already.

The example in the linked article is:

Import-Module GroupPolicy
Get-GPO -Guid 31a09564-cd4a-4520-98fa-446a2af23b4b -Domain sales.contoso.com
