I wanted to make some changes to some permissions on mass today but decided it would be prudent to backup the permissions first.

So I used icals, to do this I first ran CMD as admin, then mapped the share drive with “Net Use“.

Why didn’t I do this on the server hosting the files?  UAC gets in the way and is a pain the bum.

To backup the permissions:

Swicthes:

/t – Performs the operation on all specified files in the current directory and its subdirectories.

/c – Continues the operation despite any file errors. Error messages will still be displayed.

icacls x:\ /save c:\temp\permissions.txt /t /c

Then to restore:

icacls y:\test /restore c:\temp\permissions.txt

Hi All,

My company uses a sub domain for a satellite office, all works fine and replication takes places etc etc.

The problem I had was with DNS.  I’m based in Contoso.local and I cannot ping any device the sub-domain Sub.contoso.local without fully qualifying the domain.

For example if I ping a server1 on the subdomain using

"Ping Server1"

DNS cannot route the command where as if I type

"Ping Server1.sub.contose.local"

it works fine.

I’ve checked DNS on Contoso.local and there are conditional forwarders to Sub.contoso.local:

So how can I get around this??  The answer is to add a DNS Suffix locally or to all the domain devices via group policy:

Group policy:

Computer Policy > Policies > Administrative Templates > Network/DNS Client > DNS Suffix Search List.

Then GPUPDATE /force your client and run IPCONFIG /ALL and you should see:
