I have a domaincontroller in my network that also acts as a DNS server for my clients. DNS server is given out by the DHCP server.

Of course when the DNS server is down, our clients can't connect to the internet anymore.

I tried in the past to add a second google DNS to the DHCP, but that caused more problems than solutions.

Is there a way to enable a setting so the clients only connect to the internal DNS server when needed (like logging in) and use the google DNS for internet only?
is there a full list of rpc event ids
We have a network where there is a shared folder which the other putes use.  In each puter I use Map Network Drive so that they can find the shared folder with the files in it.

Puter holding all the  shared files is running 10.  The putters that map to it are running 7 and one is running Vista.

It has worked perfectly for years  ..  Now I have to redo Map Network drive ever other day or so.  I don't know why . Than it works fine again.  They seem to loose the network.

Anyone know why this could be happening??

Thank You


I am looking for a VB script that would allow to type full name or users name in a search box that would run against certain LDAP groups (43 groups) to confirm if the user exists. If the user exists the output should be display on the screen and save in CSV file.

These 43 groups exists in AD (LDAP).

Thank you, M
Dear Experts, I got this error when configuring RODC, could you please suggest?

"you need to specify the source domain controller using its fully DNS host name "
After registering VM "in-place" at reinstalled Hyper-V server, the guest Windows Server 2012 R2 shows "no connections are available", even there is a network connection available, it does have IP address, it can connect to the internet...

Therefore none of the crucial services start up - I can only sign in via safe mode, as this is the domain controller...
Other VMs did register without any problem...

How to fix this network connection problem?

I have just installed a new VM server. i.e. 2016 standard, trying to patch it but its stuck on downloading updates for 0%, have tried stopping and deleting everything under software distribution folder, it didnt work. Any ideas?

We have about 10 servers, and 100 workstations. The only system that cannot ping or access the Synology network storage is a Windows server 2016. I have checked network discovery and the services associated. It's in the same domain and can access a different synology nas on the same network. We called Synology and they said it was on our end. I did all the usual troubleshooting disabled firewall etc.

We have MediSoft 19 installed on 9 workstations. We have 18 users logging into their domain account. Every time a new user connects to a workstation we have to choose MediData file. Is there a way to have MediSoft automaticllay find the medidata file without manually inputting \\servername\medidata?
I know this DMZ Forest Trust type question has been asked many times.  I read most of them and have followed many of the recommendations, however I still seem to be having trouble with this.  I'll explain what I'm trying to do...

  • I have a new, 2016 functional level, forest created in the DMZ (we'll call it edge.domain, or edge DC)
  • I have an existing corporate, 2008 functional level, forest on the LAN (we'll call it lan.domain or lan DC)
  • I have created conditional forwarding zones for each domain in each DNS.
  • All necessary ports were opened between lan DC and edge DC
  • I have established a one way non transitive trust, where the edge.domain trusts the lan.domain.
  • I have several servers in the DMZ, some windows some linux, some of these servers must authenticate to the lan.domain and currently have firewall ports opened from each of these servers to our domain controller to authenticate.
  • I would like to accomplish a few things. 1) Allow administrators to log onto the edge.domain windows servers using thier lan.domain accounts.  2) Allow other servers in the DMZ to authenticate with the edge.domain controller instead of the lan.domain controllers.  3) Tighten up firewall rules to ONLY allow edge.domain controllers access to the lan.domain controllers, nothing else comes in from the DMZ.

So here's one issue so far that I'm facing.  Although the trust looks to be …
No matter what host I try to scan including the loopback - zenmap puts a line through the command and stops (see attached). Any idea why it might be failing?

Two days ago I tried to print a PDF file to a networked printer and nothing happened.  It is like the printer disappeared.  I did some digging and found a new error in Device Manager - my Microsoft Teredo Tunneling Adapter had a yellow exclamation that said the device cannot start (Code 10).  

I tried disabling and re-enabling the adapter, no luck.  I did the same for my physical NICs on my PC and no luck.  I was able to get my printer to work, but now a screen capture utility called SnagIt 9 no longer displays the library of my screen captures (many thousands).

Here is info on my system:

Windows 7 Pro 64-bit
Up to date with Microsoft updates
Have three physical network interface cards in the PC, two are disabled - only one used
For all three cards, IP4 and IP6 are checked

I tried having Device Manager check for driver updates, and was told I have the latest version.  I also uninstalled the adapter and re-installed it, but I still have this error message.  Any suggestions?
Good afternoon,

To summarize, a group of servers, can not be discovered by the HP CMDB Universal tool, throwing the following error:

error: java.lang.Exception: The object exporter specified was not found.

This error is due directly to the tool? or per operating system?

Stay tuned to your comments..

Best regards.
I am the IT person for a small company and we have a large group of engineers that need to install a wide range of software and updates on a frequent basis. I want to keep things secure but also make it so that I do not have to be present all the time.

My solution was to create a domain account named Software and I put Software into the Administrators group on each computer. When a user needs to do an upgrade or install, they send me a request, and I can give them the current credentials for Software. When they are done installing I change the password for Software. This has worked fine.

Now the problem. Users can use a previous password I have given them for the user Software. There is a laptop we use for PLC programming. About a month ago I allowed a user to install software using the Software. Yesterday I got a request for an upgrade and before I could reply I was told they got the upgrade done. I inquired how and was told they used the password I had given previously. Since the initial use of the account Software, I have changed the password for Software at least 6 times. Why was the old password still accepted?

Now I am thinking that I could create a local account for each computer and change that password, but that means keeping track of the password for that local account for 75 different computers. And will an old password still work in this scenario also?

Dear Experts,

I need your opinion on this question we have. Currently We host a SaaS environment for our customers. Due to a lot of legacy our SaaS environment is connected to the same domain controllers as our internal network and computers. Everything is very open and security is becoming a real issue. Now the question we struggle with, what is the best thing to do.

1. We completely separate our SaaS environment from their current domain. Create a new domain with its own forest. Only the administrators get a username and password in this new forest. This will make sure none of my employees can access the SaaS environment without an administrator knowing about it (which is what I eventually want to achieve).

2. We keep the the SaaS environment and our own network in the same domain and forest, and we block any access for my users to the SaaS environment based on firewall rules, leased privileged user account, and audit policies.

I don't quite know what the best option is, both bring a lot of configuring and after work hours to implement. We just want a secure environment for our customers which is compliant with ISO 27001.

Hi All,

we are doing a project in which we are upgrading all windows 2008 domain controllers to windows 2016 server (VMs)
The one which will be done first have NPS role, and is a certificate server as well (doesn't hold any FSMO roles)
any guidelines which can assist in the upgrades and demoting the old server?

Hello Experts,
We recently moved from a Netapp 2040 (7.1) to a Netapp 3210 (8.1.4P10 7-Mode).

We've noticed a significant slowdown in CIFS when accessing files. Everything is the same network, software and server wise. We snap mirrored the data from the 2040 to the 3210, changed the name and IP of the 2040, rebooted and then gave the 3120 the name and IP of the 2040 and rebooted the 3210.

Everything looks fine except for two things:

1. when we ping the NIC on the 3210 the latency is around 14ms.
2.I have a file from a program we use to determine if things are slow and on the 2040 it would open in less than 5 seconds. on the 3210 it takes 1 minute and 30 seconds.

We are currently doing a snapmirror to another system but we didn't notice any latency when we snap mirrored from the 2040 to the 3120.

We use mainly RDSH servers (Windows 2012 R2) and Windows 7 workstations. We have one file (program built in house) and it doesn't seem to load any slower on the 3210 than it did on the 2040.

I'm running the netapp system analyzer for CIFS but i dont see anyting out of the ordinary. not sure if its a protocol issue or something else.
It's wired by ethernet right beside he router

Win 10

Two iPads and iPhone all fine on wireless - getting 80 meg fast broadband

PC - Every few days www speed start to crawl for unknown reasons

Can't change the router Dns so I changed the pc Dns to google and that fixed it one day .... now problem back and customer on the phone again

It's been scanned with Microsoft Sec Ess and super anti spy and probably malware bytes I think also

What to do next / what to try ?

Should I consider adding a new network card or updating driver on present one ?

The pc itself is fast enough on applications but www speeds are so bad occasionally when other clients are ok

Home setup with 80 meg connection ....
When i go to another VLAN with my laptop, It will not get the connection from network or we can say it will take some time to get IP from new VLAN from old VLAN. If i connect the laptop from Wireless it shows connected.
I want the suggestions that i would be able to connect on diffrent VLANs with my laptop and with my netwrok.
