Hello, we're looking for a PSU, a mounting kit/bracket and pens for a Promethean AB75 board

Hello, I was just wondering if anyone has had any joy configuring the BTLS Netsweeper Authentication Portal. I've followed their guidance and got very close to what I'm after... We are redirected to the login page and when we use our AD creds it allows us to look at the page requested, if we don't use AD creds or use erroneous creds then we are blocked from accessing the page. However, we are asked to re-enter AD creds every time we change url, I would prefer to allow the user an hour of browsing before they need to re-enter creds, has anyone else had this and was it resolved? Thanks Darren

Hello, I'm having a few people struggling to get a VPN connection to our 2012 R2 server. We have a static pool of 13 addresses but they don't all get used even though there is demand from remote users ie the connection attempt is rejected even when there is enough IP addresses in the static pool. In this screen shot I'm confused as to what the 192.168.8.192 IP Address is? When the static range was entered it just appeared. Do you need enough free IP address for the range you enter plus the generated IP Address? Many thanks

I'd love to know this as well.

Hi, we've reached the maximum number of APs for our RUCKUS ZD1106 (4 indoor and 2 outdoor APs) how do we go about adding 2 more APs? Do we need to upgrade the controller? Thanks TG

Hi, asked about a /23 and got this response:- "That’s the whole idea of the vlans, it cuts down on the broadcast traffic and the 2 vlans don’t run consecutively so it can’t be made into a /23 subnet, the only way around this is to vlan the switch ports correctly."

Pretty sure the helper IP address has been added - - - Updated - - - All CISCO

From my original (poor) example:- 456.456.456.x 255.255.255.0 The gateway is the gateway on the original scope, which I thought was odd. So from my original example 123.123.123.254 - - - Updated - - - Cisco can't remember the which models but I'll find out tomorrow. - - - Updated - - - It was an additional scope. I then created a superscope with the old and new scope.

sorry yes, just representative. I should have done it differently.

Hi, our school has run-out of IP address ( 123.123.123.x/24 ) so the LA gave us a new scope (456.456.456.x/24). I added this new scope to our Win2008R2 DHCP server but the new scope didn't issue any IPs, I went back to the LA and got this reply:- The switch ports need to be configured into the correct vlan on the switches. I'll need the switch port numbers and the addresses/name of the switches they are connected to and I could do it for you. I don't remember this being necessary in the past (at other schools), so I asked another engineer at the LA and he said both scopes (new & old) needed to be in a super scope, I configured the super-scope and both scopes issued IPs, however the computers receiving IPs from the new scope were unable to see the server shares and connect to the internet. Does anyone know where I'm going wrong? Is the first LA engineer correct and he needs switch info? Thanks TraineeGeek

Thanks, lots of sound advice. I need to change the way I do some things.

Hi, this week we've had workstations losing their trust with the domain, some multiple times a day. I looked in the Event Viewer on our 3 domain controllers and there were lots of errors reported by the win2003 server, replication errors. Event Type: Warning Event Source: NtFrs Event Category: None Event ID: 13508 Date: 18/07/2015 Time: 14:23:17 User: N/A Computer: DC Description: The File Replication Service is having trouble enabling replication from PDC to DC for c:\windows\sysvol\domain using the DNS name pdc.domain.town.sch.uk. FRS will keep retrying. Following are some of the reasons you would see this warning. [1] FRS can not correctly resolve the DNS name PDC.domain.town.sch.uk from this computer. [2] FRS is not running on name.domain.town.sch.uk. [3] The topology information in the Active Directory for this replica has not yet replicated to all the Domain Controllers. This event log message will appear once per connection, After the problem is fixed you will see another event log message indicating that the connection has been established. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Data: 0000: 21 07 00 00 !... ALSO Event Type: Error Event Source: NTDS Replication Event Category: Replication Event ID: 1864 Date: 20/07/2015 Time: 15:40:35 User: NT AUTHORITY\ANONYMOUS LOGON Computer: DC Description: This is the replication status for the following directory partition on the local domain controller. Directory partition: DC=ForestDnsZones,DC=domain,DC=town,DC=sch,DC=uk The local domain controller has not recently received replication information from a number of domain controllers. The count of domain controllers is shown, divided into the following intervals. More than 24 hours: 2 More than a week: 2 More than one month: 2 More than two months: 2 More than a tombstone lifetime: 0 Tombstone lifetime (days): 180 Domain controllers that do not replicate in a timely manner may encounter errors. It may miss password changes and be unable to authenticate. A DC that has not replicated in a tombstone lifetime may have missed the deletion of some objects, and may be automatically blocked from future replication until it is reconciled. To identify the domain controllers by name, install the support tools included on the installation CD and run dcdiag.exe. You can also use the support tool repadmin.exe to display the replication latencies of the domain controllers in the forest. The command is "repadmin /showvector /latency ". For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. It was always my intention to demote our Win2003 server today so that is what I did. I tried to run dcpromo but it errored with a logon failure, so I ran dcpromo /forceremove then removed entries in AD Comp & User and AD Sites & Services. Removed the NS from DNS then ran dcdiag.exe everything passed except for:- Starting test: SystemLog A warning event occurred. EventID: 0x000003F6 Time Generated: 07/21/2015 11:17:22 Event String: Name resolution for the name domain.town.sch.uk timed out af ter none of the configured DNS servers responded.

These records are used by other computers to locate this server as a domain controller (if the specifi ed domain is an Active Directory domain) or as an LDAP server (if the specified domain is an application partition). ......................... PDC failed test SystemLog I'm wondering why we've got workstations randomly losing their trusts? Is AD healthy apart from the above error? Just got another losing trust The session setup from computer 'WIN7PWPSNB99' failed because the se curity database does not contain a trust account 'WIN7PWPSNB99$' referenced by t he specified computer. Many thanks TG

Yeah AD Users & Computers opens fine. Thanks for your advise.

Hello Everyone, I have done some research before posting and I'll be spending the evening reading the RAID manual. In the meantime... Today one of the HDDs in our IBM Lenovo ThinkServer (TD200x -[382241G]- 06) reported faulty .The RAID hardware is a IBM ServeRAID-MR10i . On the desktop we got this message:- Controller ID: 0 SAS topology error: Device not addressable. I open the MegaRAID software and one of the disks is reported as:- (Foreign) Unconfigured, Bad Also today we've had other servers and workstations losing their trust with the domain and sometime taking a few attempts to get them back on the domain. Is it just a case of replacing the HDD? If so any tips? Is the faulty RAID causing the AD problems? Will AD be corrupt? This is the warning in AD:- Log Name: Directory Service Source: Microsoft-Windows-ActiveDirectory_DomainService Date: 20/07/2015 10:27:05 Event ID: 1539 Task Category: Service Control Level: Warning Keywords: Classic User: ANONYMOUS LOGON Computer: ####.##########.###.## Description: Active Directory Domain Services could not disable the software-based disk write cache on the following hard disk.

yes, that's correct, the newer school is getting the new DfE number.
