Trying to solve Dhcp problem

Generix · 12-02-2003, 08:59 PM

Since I have the flu today, I decided to finally get rid of all errors and warnings reported in the event log of Windows 2000. I was able to do so, all except for one item:

Event Type: Warning
Event Source: Dhcp
Event Category: None
Event ID: 1003
Date: 12/2/2003
Time: 8:15:58 PM
User: N/A
Computer: COMPUTER
Description:
Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 00045A4CF6F5. The following error occured:
The semaphore timeout period has expired. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
Data:
0000: 79 00 00 00 y...

Do any of you networking gurus have any advice? Perhaps I should be contacting Earthlink (although this seems more like a hardware issue of sorts). I have searched the internet fairly thoroughly, though I may have missed something. Thanks in advance

*I have a dataquest adsl modem/router combo from Earthlink and a Linksys LNE 100TX Fast Ethernet Adapter (v4) and run Windows 2000 SP4.*

Are you running Windows 2k Advanced Server as your OS? Doy ou have more than one Network card in your computer? Can you still access the internet even though this error is showing up?

**greffov** · 12-03-2003, 12:53 PM

Do you have a DHCP you know of? If it's the router you talk about, it's probably safe to ignore it, but you might want to review the settings of the router to see if it's DHCP server allows any configuring.

Generix · 12-03-2003, 06:29 PM

I run Windows 2000 Professional with one network card. I can still access the internet fine. The reason I was concerned about this message in the first place is because I was losing sync with my DSL ISP fairly often for the first few days of being back online after four months. However, I seem to have a much more stable connection now. I don't know if I have a dhcp or not, sorry. (I'm not even 100% sure what a dhcp is actually lol) Earthlink's modem/router combo is actually a "modified" router which surprisingly doesn't have any configuration options. I guess it acts just as a single NAT. The problem with this is that I cannot send DCC's in mIRC

. I guess I need to find a new one. Thanks for your replies.

Ahh ok. DHCP = Dynamic Host Control protocol. Basically your router (earthlink) is hosting your internal network by automatically assigning IP addresses to all of your internal PC's. These IP addresses are all private and cannot be seen publicly on the internet.

Do you have any other computers plugged into the earthlink router? Do you have any other routers inbetween your router and your PC?

Try this.. go into a dos command prompt. (Start button > Run > type in "cmd" ). Once you are at the comamnd prompt type in:

" ipconfig /renew "

This should refresh the IP address in windows and give you some type of IP address. (ex: 192.168.1.101).

See if that works. because if it is then that router is indeed providing you with DHCP.

**greffov** · 12-04-2003, 02:20 AM

ipconfig /all shows which machine is seen as DHCP server, maybe that helps to figure things out.

Generix · 12-04-2003, 04:13 AM

I only have one computer pluged into the router with no other routers in between.

When I typed ipconfig /renew I got:

Quote:

The following error occurred when renewing adapter Local Area Connection: Unexpected network failure or insufficient access

At this point mIRC d/ced with "* [10053] Software caused connection abort"
I'm not sure what I should look for when I type in ipconfig /all.
Doing that before and after ipconfig /renew, no addresses changed.

Quote:

Node type=broadcast
IP routing enabled=No
WINS proxy enabled=No

DHCP enabled=Yes
Autoconfiguration=Yes

And what is the Lease obtained and Lease expires? By the way, I have a dynamic IP. I also have a related problem: I can never stay connected to mIRC over night. It almost always gets d/ced because "Software caused connection abort". I was always told that this was probably do to my firewall. Now I am not so sure. Any ideas on that? Thanks again guys

Also, this was reported in the event log when I typed ipconfig /renew

Event Type: Error
Event Source: Dhcp

Description:
The IP address lease xxx.xxx.xxx.xxx for the Network Card with network address 000XXXXXXXXX has been denied by the DHCP server 0.0.0.0 (The DHCP Server sent a DHCPNACK message).

Could this have anything to do with a disabled Windows service? I have many disabled and the ones I was not positive that I needed in manual for now. (DHCP client is on automatic and started). Thanks

*I mentioned earlier that I had 'a much more stable connection now'. Let me make that more clear. I still lose sync occasionally for unknown reasons and it is a pain (one known reason is that damn 900mhz phone on my desk....it loses sync every time someone calls....). Perhaps this problem is directly related?*

* EDIT by greffov: removed your IP and MAC address

**greffov** · 12-04-2003, 04:39 AM

Your ISP probably gives you a new IP overnight. This causes a disconnection of all internet related programs. Some care about that, others don't.

DHCPNACK is DHCP Negative Acknowledgement. It means something like the DHCP server said NO.

I believe you best ignore these warnings because they will most likely be caused by your ISP's way of doing things.

Cirga · 12-04-2003, 12:25 PM

Ok this could be something as simple as a setup issue in Windows Networking control panel. Go into your control panel. Go into Networking. Verify that you only have one Local Area Connection there. If you have two of them or anything else delete them all except for one Local Area Connection. Then check the properties. Make sure you only have one Internet Protocol (TCP/IP) in there. Then check the properties on that local area connection and verify that everything is on Obtain IP etc automatically as shown in the image I have attached.

Once that is done try doing the ipconfig /renew again.

A DHCP Lease is when a server or router actually assigns an IP address to your network cards MAC address for a certain period of time. Sometimes servers give you a lease for a 15 day period, or a 30 day period on average. So every 15 or 30 days it will assing you a new IP address which will cause you to lose connection. If your ISP is doing this every night that is just shoddy server administration on their part. You can double check this by logging into your router's config screens (if you can). If not call your ISP and ask them what is going on with their DHCP leases and how long you keep your IP before they change it. If their first tech who answers the phone is clueless ask for a tech taht knows what is going on (more often than not I have to do that when I call an ISP).

Cirga · 12-04-2003, 12:28 PM

Oh and check your Windows Services.. make sure that DHCP Client is set to Automatic.. and that it shows the "Start" button greyed out. That means its on.

Generix · 12-04-2003, 05:08 PM

Yes, one local area connection. Yes, one TCP/IP installed. Yes, obtain automatically. Yes, DHCP Client is on automatic and started. My lease is for 10 days. And thank you to greffov for the removal....I am on many drugs right now and not completely there. I guess I'll try contacting Earthlink to see what they think. I guess that there isn't anything else to try unless a service not running is responisble. Thanks for your help guys, I appreciate it =D

Cirga · 12-05-2003, 01:28 PM

One last thing you could try. Is maybe putting some kind of router inbetween you and the earthlink router? Sounds like the hardware they installed for you has a problem. The fact that you can still connect to it makes me think maybe you have a static IP address you should be using?

When they installed it fo ryou did the installation tech do anything on your PC or did he just plug it in and leave? Ask them i fyou should be set up on a static IP address instead of DHCP. Just seems very odd to me.

But at least its not a problem with "your" PC. So dont take any flak from them if they start trying to jide you with "oh you need to reboot or buy swiss scheese to make it work".

Generix · 12-05-2003, 04:12 PM

I don't have another router at the moment, and if I were to buy a new one, I would just replace this one. Unless they made a huge mistake and gave me a static IP, I am pretty sure that I don't have one (It's an extra $10 per month). No one installed the hardware. Only the router is from Earthlink, so I put in the network card and hooked up the router (I didn't do anything special to the PC). On checking the event log, I haven't got that warning since the DHCP error. I haven't gotten any entries in fact (neither have I rebooted). Time will tell I suppose. Thanks for your persistance Cirga

. Any ideas on what's causing the mIRC d/c's?

Cirga · 12-05-2003, 06:59 PM

If you cant DCC in IRC it coudl be a number of things actually. First off do you have "any" firewall or virus protection software installed on your PC?

Which IRC client do you use when you connect to a server? For that matter which IRC server are you connecting to that you are having trouble on? Do you have the option to prompt for DCC when requested checked correctly in your program options?

Are you able to receive files through DCC? Or can you not receive nor send?
