Cisco ASA: NAT 2 Public IPs to 1 Private IP
KB ID 0001582 Problem I got asked today if this could be done. My first response was ‘why?’ I cant really think of a use case for this. But a client had this on their previous firewall and were migrating to a virtual ASA, and wanted the config replicating. So I built something like this; Solution To be fair, my first thought was ‘why not simply add an additional internal IP to the web server, and NAT the second...
Mailbox Move ‘StalledDueToMailboxLock’
KB ID 0001581 Problem I was doing a migration from Exchange 2007 (on prem) to Exchange 2013 (on prem), this week. I had a number of mailboxes that were ‘StalledDueToMailboxLock’. Solution Nice easy fix, on the Source and Destination Exchange severs, restart the ‘Microsoft Exchange Mailbox Replication Service’. Wont this break my Mailboxes! No, it will interrupt the migration process, (which is already stalled)....
Virtualising Hyper-V ‘Validation Fails’
KB ID 0001580 Problem Normally if you saw this error, it would mean that you didn’t have the advanced virtual extensions turned on, in the physical machine’s BIOS. But here I’m installing on Hyper-V in a vSphere/ESX environment; Validation Results The validation process found problems on the server which you want to install features. The selected features are not compatible with the current configuration of your...
vSphere: Migrating vSwitch PortGroups and VLANS
KB ID 0001578 Problem Over the past few weeks I’ve been doing some work for a client that involves me adding some new ESX hosts. These will be setup the same as their existing ESX hosts. That’s fine, but they use standard vSwitches and have A LOT of port groups and VLANs. I could sit and create them all manually, and tag them onto the the correct VLANs, but something that’s boring and repetitive is better solved with...

VMware: Upgrade Errors
KB ID 0001576 Problem This weekend I had to upgrade some servers from VMware 5.5 to version 6U3, (that’s the latest supported version, on the hardware I was using: HP BL460c). As the VC was at version 6.5 I couldn’t use the built in update manager, so I had to use the ‘offline bundle’ method. TWO THINGS then jumped up and bit me; Problem 1 [DependencyError] File path of ‘etc/init.d/hp-mst.init’ is...
Cisco SFR Cant Ping its Default Gateway?
KB ID 0001575 Problem This is a strange one? I was deploying FirePOWER to a pair of ASA 5550-8-X firewalls in Active / Standby failover last week. After each SFR was updated (via ASDM.) I could no longer ‘ping it’, the SFR itself could ping everything on the same VLAN, APART from its own default gateway, (which was an SVI on the Cisco 3750 switch it was connected to). This happened every time I updated the SFR, (or...
Load Balance IIS with Microsoft ARR
KB ID 0001573 Problem If you have a lot of IIS servers, and want to load balance between them, then you can either buy a load balancer, or use Microsoft ARR (Application Request Routing). Note: ARR does a lot more than simply load balancing, e.g. it can perform caching, and complex web routing, and even SSL offloading. Here we are just looking at load balancing. I’m going to deploy TWO ARR servers in my DMZ, here I’ve got...

Find All HP iLOs on your Network
KB ID 0001571 Problem I had to find all the HP iLOs on a client network today, I could have got an IP scanner and then sorted the results for HP devices, but I would have ended up with switches, printers and God knows what else! If only there was a PowerShell command I could use? Solution There is! You will need to download it though, (HPiLOCmdlets-x64,) extract them to your C: drive. Here I’m installing them from PowerShell,...
