  • 2. disk management from mmc
    I am trying to access disk management on a few remote servers. The servers are running both 2000 and 2003 (all updates). I am trying to connect from XP Pro, sp2. I can connect to some of the servers, but others give me an error saying that disk management failed because it is not in the exception list for windows firewall. I can connect to these servers from another server mmc console but not from XP. Why am I having trouble with just these few servers? Also, I have windows firewall disabled in group policy and if I go into the control panel, firewall settings, it says it is disabled. Any ideas?
  • 3. Newsgroups
    Can I access newsgroups(other than this specific set of newsgroups)using my hotmail account, and if so, can someone please explain how I go about doing it. Many thanks, Steve C
  • 4. how do I manually configure Windows Network Wizard settings
    I've just set up a home network with one computer as an internet connection server and one as a client. I used the Internet Connection Wizard on both machines (one has XP pro and the other has XP home), but I'd like to access all the settings that the wizards set up so that I can monitor/change them when I need to. I understand that this might screw up my network but I'd like to have this control. Specifically I'd like to get to the DHCP and other LAN specifications that the wizard configured on its own. Thanks
  • 5. Problems with networking LAN
    I have 2 computers running XP Home. They are connected to an EDIMAX BR-6104K router. The router connects to my ADSL modem. I can connect to the internet from both computers, but the computers cannot talk to each other (not ping, nor shares, they don't appear in the workgroup, etc)... Each computer can ping itself and the router. The router is set up as a DHCP server. I tried using static IP but it didn't help. What am I doing wrong... I do have SP2 and the Windows Firewall is enabled (with exceptions for File and Printer Sharing which were added via the network setup wizard) PLEASE HELP!!!

ping loopback with tcp/ip disabled

Pinging the loopback address tests confirms that TCP/IP is running, correct?

Is there any reason that I can still ping the loopback address even though I 
have disabled TCP/IP? Or is my understanding of what pinging the loopback 
address does wrong?

In article < XXXX@XXXXX.COM >,



The loopback address is internal to the TCP/IP stack and can be used
even with no installed network adapters.

How did you disable TCP/IP?

I disabled TCP/IP through the properties of the connection under the 
networking tab. A lab in the Microsoft 272 book instructed me to disable 
TCP/IP by unchecking the box there, which should keep pinging the loopback 
from working. It did not, and my instructor did not have an answer as to why.

Does unckecking the box not actually disable TCP/IP for the connection?

In article < XXXX@XXXXX.COM >,



Unchecking the box disables TCP/IP on that network connection, and
only on that network connection.  It has no effect on other network
connections, and it has no effect on the loopback address.

The loopback address isn't associated with any network connection.
It's internal to the TCP/IP stack, and TCP/IP runs even when TCP/IP
isn't bound to any network connections.   To demonstrate that, you can
un-install all network adapters, open a command prompt window, and use
the "route print" command to show the TCP/IP route table.  It will
show:
  
   127.0.0.1  255.0.0.0  127.0.0.1  127.0.0.1  1

1.TCP/IP computer can ping world, world can't ping computer

Hi

I'm having a really strange situation going on with one of my Win2000
computers.

As the subject line states, it can ping and access the world (within
and outside of the LAN), however, no other computer can ping it (ie.
ping 192.168.2.3).

This machine is able to browse the web and ping everywhere, but no
other computer can ping it, which means that my XPPro laptop, which
doesn't have the netbui protocol installed, can't access the shares on
the w2k computer.

This machine is connected to a belkin 4 port router (which acts as the
DHCP server). If I set the machine to use a static IP address, it
can't browse the web at all.

I ran winsockfix.exe on it, which kinda resolved the internet access
problem (as long as the computer uses a dynamic IP address).

Also, I have no firewall running.

I already tried replacing the network card (as instructed in other,
similar, threads).

Next stop seems to be a full reinstall of windows 2000 unless someone
comes up with another clever idea.

Thanks in advance!!!!!

Alex

2.Failed TCP/IP Internet Loopback Test Error Code NC315-5W

Hi,

I ran PC Doctor to test the connection on my network adapter (Realtek 
RTL8139/810x Family Fast Ethernet NIC) 

The test failed on the following:

Failed TCP/IP Internal Loopback Test Error Code NC315-5W

Failed Network Communication Test Error Code NC315-1W

If anyone could advise on this it would be much appreciated.

Thanks in advance.

4.std tcp/ip verses hp std tcp/ip printer port

What is the difference between...
[standard tcp/ip]...
and...
[hp standard tcp/ip]...
when setting up a local printer port?
Any insight will be appreciated.
Thanks, Tracey


5.Microsoft TCP/IP V6 and Internet Protocol (TCP/IP) in network settings

Just noticed that I have both Microsoft TCP/IP V6 and Internet Protocol 
(TCP/IP) showing in network settings.

Is this (a) normal, and (b) likely to cause a conflict ? (XP Pro machines)

Should I remove one or the other?

Jeff
