Just wondered what peoples stances are on flash player, do you still install it on your images. Thanks

I have been asked to draft up a policy for the school in regards to school social media accounts. The idea being that staff are aware of set procedure for having an online presence in the school name, facebook, twitter, youtube etc. Has anyone done this and have a policy they would be willing to share, or any thoughts on what would be a good system to have? I have some ideas but would be interested in what anyone else.

Nice one, thanks. Just wanted to make sure.

I have an old HP x1600 storage array which has 12 1TB drives. The Caddie shows as 7.2k SATA MDL and the drives in the Caddies are all Seagate Barracuda ES.2 1TB 7200 SATA drives. I have always replaced failures with a the same drives from HP but these Seagates seem to be failing a lot. Come back in after the Christmas break to find 1 drive failed and 3 in predictive failure. its the storage server for my veeam backups. Can I just replace then with say WD Red 1tb drives or do you thin I can only use the Seagate ones? Cheers

We block Games using the filters but really it's a classroom management issue, we provide Lanschool to aid teachers in that. We have a Video Games Club on Tuesday where the studentst get to play things like Battlefield 2 in the IT rooms as a Lan game on an internal dedicated server, which has become very popular.

Created a profile within Apple Conf 2 - but when I click on the IPAD and add the profile I just get invalid profile, no pointers as to what might be invalid. Anyone able to point me in the right direction? Cheers.

Even if you don't have cisco gear it's worth using I found it very useful and we use HP Procurve.

Yeah, Hyper-v we were using.

Update and problem found..... OK the problem was down to a faulty VM. It was our Bitdefender AV control Linux VM that was causing a large amount of synchronous sequential reads and writes for long periods on the storage array. This was slowing down the whole array and thus the servers stored on it. Turned off the VM and everything back to normal, now to contact Bitdefender to find out why

So an update, I have removed all traces of Vlans from the switches checked switch interlinks for loops etc can't see anything. Checked DNS and that appears to be working fine as tests from dcdiag /test:dns all pass. Still having a nightmare though and it all seems centered around file browsing and internet browsing and printing, databases are working fine such as Sims and Catering, but I am now at a loss.

I say router, I mean L3 switch HP 5406Rzl2

I have a router, but not great on NAT, will have to have a read up on that. Thanks though.

Yeah it's the range given to us by the LA, I did introduce vlans this summer to break it up into smaller segments but had to change back after the LA internet would not work as it was dropping our vlan traffic. Now I have all this slowdown.

Ran those all tests passed, it's almost as if computers are having to discover everything for the first time.

I changed all the subnet masks to /24 and the gateways to the vlan interface, and then changed them all back again to /16

HP Switches with the odd 3com, I should add that I moved to vlans and then back to everything in default vlan again during the summer (long story) so the gateways and subnet masks were all changed from /16 to /24 and then back to /16.

Hi all, Very strange network problem at the moment, we combined our admin and curriculum networks over the summer into 1 and now we seem to be having major network lag. We also added a new core switch and upgraded some links to 10GB. Ping times are fine, the problems I am having are with file access times, login and internet. You can log in eventually and when you get in a click on a folder you end up waiting for the folder to display the contents while the green bar moves slowly up, network printing is slow everything is just deathly slow. Any ideas as I am beginning to lose the little hair I had in the first place.

I added ip route 0.0.0.0 0.0.0.0 10.217.0.1 and that did the trick, many thanks for all your help guys I have learnt a lot.

Thanks for you help guys I am now getting ip addresses issued by my dhcp server do I need to setup a route for my switch to the LA (internet) switch to enable them to work together?

so what would the gateway be on the servers as the 10.217.0.1 current gateway is the LA switch which I have no access to, thanks for your help so far.

What if I want to keep my servers on 10.217.0.x address and my switches on 10.217.3.x or am I better rolling them all into the same range? Is there a way to make the switch know of the 10.217.0.x range ?

10.217.0.31 is the dhcp server, I have set a scope up as above so for example I have a scope set to 10.217.10.2-10.217.11.254 and for vlan 20 the interface ip is set to 10.217.10.1. The core switch is set to 10.217.3.1/24 on vlan 1 with its gateway set to the LA switch which is the 10.217.0.1 gateway. I am unable to ping the core switch for some reason from any machine on the address I set it to. Something has gone wrong somewhere....

Changed that but still no joy, a bit more info, I have complicated matters more as I am trying to move from a network based on a mask of 255.255.0.0 with no vlans to a vlan based network. My servers are all currently in vlan 1 at the moment, some or using 255.255.0.0 and the DCs including dns and dhcp I have moved to /24 but are still in vlan 1. The broadband switch provided by the LA was our old gateway which is the gateway the servers point to at the moment.

I think that is where I have have gone wrong, with the subnet mask. (I am new to subnetting) So I am looking to have a range of DHCP addresses available for students from 10.217.10.2 - 10.217.11.254 so for that vlan what mask would I use 255.255.254.0?

Hi all, Having a small problem with DHCP farming out address to my new vlan setup. I have setup up a dhcp scope 10.217.10.2 - 10.217.11.254 -- 255.255.252.0 with router option set to 10.217.10.1.
