| After I promote
my Windows 2000 domain controller (DC), its DNS
suffix doesn't match the domain name. How can I
fix this problem? |
After you run DCPromo, you might receive a NetLogon
event (ID 5781) or other dynamic registration errors
in the System event log indicating failure to dynamically
register DNS records.
You can't rename the computer on the Network Identification
tab. To correct this namespace problem, complete the
following steps:
- Use DCPromo to demote the DC to a member server.
- In the Control Panel, double-click System, click
the Network Identification tab, and select the Change
primary DNS suffix when domain membership changes
option.
- Run DCPromo to promote the member server to a DC.
If you haven't run DCPromo yet, complete these steps:
- After upgrading to Win2K, use regedt32 to navigate
to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\
Parameters.
- Set the data value of the SyncDomainWithMembership
Value Name to 1.
If you must add this Value Name, it is a REG_DWORD
data type.
How can I configure
how long the DNS cache stores positive and
negative responses?
|
By default, Windows stores positive responses in
the DNS cache for 86,400
seconds (i.e., 1 day) and stores negative responses
for 300 seconds (5 minutes).
To modify these values, perform the following steps:
- Start a registry editor (e.g., regedit.exe).
- Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\
Parameters registry subkey.
- From the Edit menu, select New, DWORD Value.
- Enter the name MaxCacheEntryTtlLimit to change
the positive cache period or the name NegativeCacheTime
to change the negative cache period, then press
Enter.
- Double-click the new value, set it to the desired
number of seconds (e.g., if you entered the name
NegativeCacheTime, you could set the value to 0
to stop Windows from caching any negative responses),
then click OK.
- Repeat step 5 for the other value, if required.
- Close the registry editor.
- Reboot the computer for the changes to take effect.
How can I enable
my web site to be accessible?
|
We are all used to entering www.<domain> for
a web site, such as http://www.yahoo.com/, however
www is just a normal DNS host record and if you want
your site to be accessible as just <domain>,
e.g. yahoo.com just create a blank host record.
In Windows 2000 to create a blank host record for
the domain perform the following:
- Start the DNS MMC snap-in (Start - Programs -
Administrative Tools - DNS)
- Expand the server - forward lookup zones - DNS
domain
- Right click on the domain and select 'New Host'
- Leave the name blank and just enter the IP address
(check the create associated pointer record box)
- Click Add Host
A new host record will be listed of the form:
(same as parent folder) Host <ip address>
To do this on NT 4.0 for the domain ntfaq.com at
address W.X.Y.Z, do the following:
- Stop the DNS service:
C:\> net stop dns
- Edit the file ntfaq.com.dns (found at %systemroot%\system32\dns\*.dns)
- Find a record that looks like:
www IN A W.X.Y.Z
- Add the following record below:
@ IN A W.X.Y.Z
- Save the file
- Restart DNS Service
C:\> net start DNS
