I have a network I've inherited in a secondary school.
We have a fibre-optic backbone with gigbit switches linking together all the classrooms / buildings on site.
We have four Domain Controllers
1 x Exchange Server
1 x SQL Server
1 x Backup server
1 x NAS box
There are 1000 students, 70 teachers, 30 support staff.
400 client computers running XP Pro
We are on a support contract for the Windows Servers (as well as hardware warranty). Each Domain controller adds £750 to the support cost.
In 12 months time I plan to ditch the support contract altogether, but in the meantime I think I can reduce the DCs to two, thus simplifying things AND saving the school £1500 pa.
My question is this:
In what way might I need to improve the spec of the remaining DCs to cope with the demand?
Do I need to think about processor speed? RAM? Network connections?
The servers have two Xeon 3Ghz (single core processors); 2 Gb RAM; 1 x fibre and 1 x Gbit network connections
Services across the 4 DCs are:
Print Serving (40 printers)
User accounts (roaming profiles)
I don't have the budget for hardware replacement (new Servers) this year.
You would need to look at upgrading the memory on the Servers if you are going to start running multiple applications on one box. Your network cards/connections seem to be fast enough and the processors
Network Monitoring is essential to ensure that computer systems and network devices are running. Use PRTG to monitor LANs, servers, websites, applications and devices, bandwidth, virtual environments, remote systems, IoT, and many more. PRTG is easy to set up & use.
So you have two Windows Servers and you have a directory/folder/files on one that you'd like to mirror to the other? You don't really want to deal with DFS or a 3rd party solution like Doubletake.
You can use Robocopy from the Windows Server 200…
I guess it is not common knowledge to most Wintel engineers/administrators: If you have an SNMP-based monitoring system in your environment (and it's common to have SNMP or Syslog) it's reasonably easy to enable monitoring of the Windows Event logs,…
Windows 10 is mostly good. However the one thing that annoys me is how many clicks you have to do to dial a VPN connection. You have to go to settings from the start menu, (2 clicks), Network and Internet (1 click), Click VPN (another click) then fi…
