he operation did not complete because the media is write protected - Pt2

I didn't expect to have to revisit this but my recent DR test has highlighted another issue along the same lines.

Trying to recover the same server again and the drives once again were not writable. No problem I know how to fix that. In to Diskpart and ...oh no hidden volumes. What is going on?
A quick check and the volumes are set to read only, but are not showing as hidden.

A quick look through the list of commands available in Diskpart revealed the Detail command, running Det Vol on an affected volume gives a listing of all the attributes something like the following

Read-only                          : Yes
Hidden                               : No
No Default Drive Letter    : Yes
Shadow Copy                    : Yes

I had a look at some other drives and it would seem the 3 Yeses should have been 3 Nos, or at least all the drives had a full house of Nos.

So I ran

Attributes Volume Clear Readonly
Attributes Volume Clear ShadowCopy
Attributes Volume Clear NoDefaultDriveLetter
(NOTE there are no spaces in the attributes)

And all of a sudden the drives are writable again. Whilst the hidden attribute is visible when listing the volumes none of the others are until you list the details of and individual volume.

This slight change in behaviour may be connected to an update to the Dell HIT kit that was done between the last time I tried to mount the drives and this time, as this only happens on drives that have their replication controlled by the Dell ASM.

As is often the case just when you think you have nailed it something crops up to prove you're not quite as clever as you thought you were.

Scripting DNS entries

For reasons to do with DR we needed to change our IP addressing scheme, either for our servers or for our PCs and printers and what not. Obviously changing PCs and printers was a whole lot easier due to the possible issues of inept developers’ hard coding IP addresses causing no end of problems with re-addressing the servers. This has entailed changing all the DNS entries for our printers, (whatever happened to the paperless office?) That in itself is no real challenge, they all have web interfaces so a quick connect and amend the setting then next printer. Updating the DNS entries was going to be a bit tiresome so I did a quick Google on how to do this with a script and up popped DNSCMD. You can run this from a CMD box on your PC, the main options you need to know are /recorddelete and /recordadd. To delete a record you simple need to type dnscmd <ServerName> /recorddelete <ZoneName> <NodeName> <RRType> <RRData>[/f] What does all that mean? Well i

Enterprise Vault - Failed Exchange Task

Here's another weird one. Enterprise Vault, we use this for e-mail archiving. It does a reasonable job. Probably no better or worse than any similar product. A couple of days ago I noticed that there was warning that it hadn't archived anything from one of our mailbox servers for a couple of days, not big issue as there is just a couple mailboxes on there as it used for testing at the moment. I had a look at the associated task and it was stopped. Started it and it failed. Error in the event log looked something like below The Task 'Exchange Mailbox Archiving Task for EXCH' failed to log on to Exchange server 'EXCH' using mailbox 'SMTP:EnterpriseVault@symantec.local'. Please ensure the mailbox has not been hidden, that the server is running and that the Vault account has sufficient permissions on the server. I went through every conceivable setting in AD, EV and Exchange trying to work out what had happened and why it wasn't working on thi

Windows Phone to iPhone - a painful transition

Windows Phone died a death due to a whole heap of incompetence from Microsoft.  My phone was an old Nokia 925, about 4 1/2 years old and bought and paid by my company. There were always low requirements for company phones, if it rung and you answered it, all was good. Then Hangouts reared its head (Google want to destroy MS, so WP support) but third-party support gave a stay of execution. The final nail was a requirement for out of hours support software that had no app for Windows Phone. I had to be “downgraded” to an iPhone 6s (yes, it is a low spec 2 version old iPhone, better hardware than my 925 but not really up there as a current version, how my company loves their staff, buy expensive crap rather than cheap crap). Stuff that just worked on my old phone, now needs 'me' to be re-engineered to work the Apple way.  This is only slightly less bad than the Google eat all your life and sell it back to you way, but it is like stepping back in to the 1990s Microsoft way
