I am writing this from my son's computer, as I have lost my wi-fi connection at my house. How do I get it back?
I have looked at the modem and router. They still have the right number of icons lit on their dials. I phoned Netgear and got an answering machine, and was unable to get the help I need.

I am wondering if this info can help you diagnose for me: Recently there has been a third sentence in the window drop-down [when I clicked on the wi-fi icon.] It said something about recommendations. Shortly after this I lost wi-fi to my computer.

Also and perhaps . . . Do I have a security problem?
In System Preferences > Wi-fi . . .  I see most networks have Security labeled WPA/WPA2 Personal. I have just WEP.

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 "
Hello, so I have this customer who would like to have his Windows server shared folders totally invisible to non-domain users.

The users don't have access, but he actually wants them to NOT see the folders, either.

So I was wondering, is this even possible? I never tried this, I was never asked to try this and I wasn't able to find any solid reference during an admittedly hurried search on Google.

Can someone help me? The server is a Windows SBS 2011 Standard.

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?
Hi Experts,

I want to share a folder on my computer to other computers on the same local area network.
I did these:
1. set all the computers in the LAN (including mine) to the same windows WorkGroup name;
2. configure a folder on my computer to share with Everyone for full control.

When I tried from another computer in LAN, my computer with the shared folder can be found in the network, However, I was asked for username/password when I tried to open that folder.

I want to ask, is there a simple way to share a folder on my computer to everyone in the network without needing other people to enter username/password?

More details: I want to do it as simple as possible, trying to avoid using ActiveDirectory or buying other equipment. The LAN I am using has a wired router. My computer has Windows 7 home premium, other computers on the network have either Window 7 or Windows 8.

Thank you!

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?
In our linux server we  there are 2-bond interface  has been configured.

server IP = 10.X.X.X
bond-0   = 192.X.X.X

when we try to ping  destination server IP, it was not reachable.
when we traceroute/ping  request to target server , the output getting like below
#from 192.X.X.X icmp_seq=54 destination host  UNreachable

very strange to get this kind of output.

Source should be Server IP, where as it giving us reply Bond-0,  This had some partial impact some service.
Kindly advise how to resolve this issue.
One of my client computers is giving us difficulty when trying to RDP into it.  I can ping the machine & get a response, where I'm confused is the IP that's returned doesn't match the host name.  I ran ping -a to check this, which returned a host name that was joined to a domain that has been decommissioned for well over 4 years.  Ran nslookup of IP it returned the same odd host name joined to the current domain.  Then I ran nslookup using the odd host name it then returned the odd host name, joined to old domain.
Like many I am scripting using netsh to change IP addresses - I am stumbling at a common area, the part where teh connection name has to be known ahead of time.
Its a laptop so I only have one hardwired lan port and one WiFi port which is rarely used.
Ideally I want to rename the connectionname to what I need to use it for, i.e. "Radio", "Building7", "VPN From HELL"  etc.  when I change the IP settings.

That of course makes the script fail since [netsh interface IP set address] needs the it doesn't know what the current connection name is when I run it.
How can I work around this?  - my searching reveals it's been an issue that many have tried to solve. Surely there is another wat tyo address this single port ?
Hi experts

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 …

Hi all,
I have created a new forest, Forest A is in 10.10.x.x range and new Forest B is in range 10.1.x.x, we have 5 sites.
What DNS changes are required between two forest? how can I synch them so both forest can communicate with each other and across other DCs which are on new subnet.
In DNS forwarder should I put IP and FQDN details of new forest and vice versa?
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?
Hi Everybody,

I have problems in opening some files from a specific computer on my network. I can open the files from other stations but for some reason some specific files can be listed but not acessed from one machine. When I try to open the file I get a message similar to this:

   Windows cannot access \\servername\sharename\filename.jpg

    Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose.

   See details: error 0x80070002 the system cannot find the specified file.

When running diagnose I find no issues...

I'm the domain admin. I can write other files to the shared folder and have full access to the files I put there. I can open the files if I access them from other computer.

I have seen no permissions diferences between the files I can read and the files I cannot access.

This network share is mounted via a group policy for every computer on the network.

I suspect there is something wrong in the specific station. Any suggestions?

Thank you!
I have two active directories, one called contoso.local (100 users) on site A and another called traders.local (300 users) on site B. I have a hardware based VPN between the two sites. What is the best way to go about consolidating the two active directories. I would like to ideally move contoso into traders. Both sites have exchange servers just to add complexity! thanks
Hi All,

Need assistance by keeping in mind it wont impact on existing forest :-) we are single forest single domain environment, want to create a new forest. how it can be done?


 It is a small office with a windows 2012 R2 standard that is configured as a Domain Controller, DHCP, DNS and file and print server.

The DHCP scope is to
All workstations and other devices including DVR and VPN clients get their IP from DHCP dynamically or there is a reservation for them such as DVR, therefore I can see all devices under Address Leases in DHCP Console.

An annoying device seems to have dynamic IP and it is in a range of the DHCP scope ( , however the DHCP does not show it under Address Leases.
The Arp command indicates that the IP is dynamic. The Advance IP Scanner under find it but cell under NetBIOS group, User and Date are blank The only cell is the Manufacturer and MAC address. I looked around and I don’t see any device that be manufactured by NetGear and the more confusing is that when at the server I run Arp command it indicates that the IP type is Dynamic. so I must assume there is another DHCP server in the network such as router/firewall but I use SonicWall and the DHCP services is disabled.

Can anyone help please ?
