Go to Active Directory Domains and trusts. First right-click all the domains and select "raise domain functional level". Afterwards you can right-click Active Directory Domains and Trusts and selec "raise forest functional level". It is very important first to raise ALL the domains to 2003...

Hello, In my domain I get the following warning every 10 hours: The currently selected KDC certificate was once valid, but now is invalid and no suitable replacement was found. Smartcard logon may not function correctly if this problem is not remedied. Have the system administrator check on...

Isn't your SMTP service limited to 150 concurrent connections?

In IIS you have an option to specify host headers. This lets you answer your webserver to a request from e.g. www.domain1.com to port 80 for instance, and on the 2nd website you configure the host header with www.domain2.com and port 1080. If a client looks up www.domain2.com it will...

Hi, As lots of you probably want to migrate off your Exchange 5.5 box, I do have an interesting tip for - by most of you preferred - in place upgrades. As far as now it worked yet everytime for me. Here it goes... 1. Backup the original server using NT Backup (backup the C and D drives). 2...

Hi, I have once seen a small presentation about quarantine networks. It goes as follows. 1. Laptop looks for network and connects to a quarantine network. 2a. If laptop is external laptop it remains in the quarantine network. 2b. If laptop is member of domain it gets verified whether it has...

1. Add your new scope to the LAN thrusted thingy in ISA (if you will use a different scope). 2. Change internal IP. 3. Restart ISA services if it didn't ask yet to do so. Microsoft, not just A company

You need to have ISA in integraded mode (FW+proxy) for that. FW mode is minimum requirement. FW mode requires 2 NICs. HTH, Beboen Microsoft, not just A company

Well, I've passed 70-216 a while ago in the VMware 3.x era... It the total # of virtual machines depends on your hardware (mainly memory) but I guess that's not the answer you are looking for. Theoretical max I don't know but I guess it was something around 125. I've run tests with up to 8...

I suggest first you set up your new DHCP. Then on the old DHCP you take a short lease time and un-authorize and after a day or two (depending on your configuration) you can take it down. I think there is a way to back up DHCP settings but I haven't done that either before. This is the quick and...

Why would you transfer all your DHCP records? I would just reconfigure the new DHCP with the appropriate options (normally it isn't that much work) and then shut down the old DHCP server.

You can block your router for broadband requests (by default this is blocked) or you can temporarily shut down the DHCP relay.

Hi, In DNS you convert fully qualified domain names (e.g. computer.department.company.com) to an IP - or vice versa. WINS uses the same names as NetBIOS names and converts them to an IP address (thus as in the example it just links "computer" to an IP). Since WINS uses IP address to convert...

Hi, Hmm, apparently you have misconfigured your firewall. You say in your 1st post: "I have ADSL and my port 25 is opened on my router pointing to my DNS server." You have to open port 25 and let it point to your mail server, not your DNS server. Hope this helps, Beboen

hmm, so far I haven't received a warning yet. Strange, because actually does it matter which time server you get the time from? time.nist.gov has given problems before when I used it (something "invalid time format") why the 0x1 tag which some technet/kb articles talk about?

it says time.windows.com ps: I've read in a technet article it should say time.server.com,0x1. Though I've never found what the 0x1 is for and without it it works fine too.

I still have the same error: Time Provider NtpClient: This machine is configured to use the domain hierarchy to determine its time source, but it is the PDC emulator for the domain at the root of the forest, so there is no machine above it in the domain hierarchy to use as a time source. It is...

Hi, My w2k3 forest root complains it is not set as a reliable time server. Here's what I did so far: 1. net stop w32time 2. net time /setsntp:time.windows.com (though I'm not sure this is the optimal way to do it; might be only necessary on forest root) 3. w32tm /config /reliable:yes 4. net...

On a single, try ipconfig /flushdns, then ipconfig /registerdns. (just for testing) Check your DNS server whether the client entered itself into DNS. I also recommend to forward DNS queries to your ISP's DNS servers (this is done only on your DNS server).

Yes you can. Make a trust relationship between both the domains. Depending on what you want make one or both domains a trusted or trusting part of the relationship.
