OVA / OVF Deployment Gets Stuck ‘Validating’

KB ID 0001664 Problem I had this problem (on sphere 6.7) the other day when trying to deploy some OVA files on my test network. Solution Well as stated elsewhere I tried reconnecting to my vCenter using its FQDN, this didn’t solve the problem, using Flash or HTML5 didn’t cure the problem either. What did cure the problem was using a different browser! I switched from IE to Chrome and it worked fine. Update: I Also cured...

Windows Server – Disable ‘Defender’

KB ID 0001710 Problem I got a call last night to help out a colleague, this involved using a ‘dubious’ piece of software that is very old, (I wont elaborate further). But to run it on a modern Windows Server is nearly impossible. The host detects the software as being infected (It may well be, but I’ve never suffered). So I need to keep the software in a password protected Zip file. And only extract it on a Virtual...

Adsense: ‘We’ve detected an error on your IAB TC string’

KB ID 0001709 Problem A couple of weeks ago I logged into Adsense and saw this; ‘We’ve detected an error on your IAB TC string on one or more of your sites or apps. These errors may affect your ability to serve ads to European users. A detailed report is available for you on the EU user consent page’. Solution Well all of that made no sense to me, so I downloaded the report, which is a spreadsheet and it looked like...

Can I ‘Shrink’ My Exchange Database?

KB ID 0001706 Problem Saw this asked in a forum today, and my response was; It never gets smaller, if you delete things out of it, it just creates more ‘whitespace’ within the database, unless you; a) Take it offline, and defragment it using eseutil. b) Move the mailboxes out of it, to another database and delete it. Which is true, but even Microsoft say you should not need to defragment a database! Before you do anything...

Which Firepower To Replace Your ASA 5500-X?

KB ID 0001705 Problem Well  the ASA5516-X was the last one to go end of sale. You may be able to get stock of the remainder of the ASA5500-X series as people clear their shelves, or they may be available as ‘refurb’ stock but they are disappearing. So you would think that the replacements would be better documented? Well it’s sketchy at best, and when you look a the data sheets for the new FPR range the links on...

VMware: Cannot Resize a VMs Hard Drive?

KB ID 0001704 Problem One of the lads in support messaged me this week, he needed to raise the size of the hard drive on a VM, and the option was greyed out (not available).  Solution Now assuming you actually have the rights to do this, the problem is ‘nearly always’ that the ‘disk’ in question has an active snapshot on it. Remove your snapshots first. Now you can raise the size. Don’t forget: In your OS...
