BEFW11S4 limited connectivity DHCP server not contacted

We have a network that has been running fine until a couple of days ago. We have changed no settings, yet now some of our wireless computers get the limited or no connectivity error. They are failing when trying to get the IP address assigned.
We're running 128 bit WEP encryption. My desktop machine which is hardwired to the router is fine, a hardwired network printer adapter is fine, and oddly enough two machines running Vista with a wireless connection are fine. It's my laptop, and a couple of my kid's laptops, all runnning XP Pro SP2, that are having problems.
I've tried ipconfig /release and /renew. The /renew times out, unable to contact the DHCP server.
I also tried the EasyLink Advisor software on my laptop. t tells me I need a wired connection.
One other piece of information; occassionally one of my sons have said they could not connect to the internet (on on of the XP machines) and I have powered the BEFW11S4 off an on, and then they were able to connect. I've never had this problem my laptop. But that's not working for anyone now.
I am at a loss as to why a network configuration that has been working perfectly well for over a month would selectively stop talking to computers with a certain operating system. Unless Microsoft has pushed an XP update recently that might have broken things?

have you tried upgrading / reflashing router's firmware .. if not , try it..after the upgrade , reset and reconfigure the router..check whether it makes any difference..

DHCP Server not giving out IP Address to APPLE iPhone

Hi, First off, I hope this is the correct forum....
A little background, I have a very nice 16GB 3G iPhone (from Apple of course). It has no problem connecting to my wireless access point (cisco 1240). I have an old windows server that I can turn on as a dhcp server and it gets an address back right away, however my mac server (10.5) will no give it an address and I do not understand why. Here is the log.....

DHCP server not reasigning IPs

Hello everyone,
We're having a big issue with our DHCP server (MAC OS X Server 10.6.4), because it runs out of IPs, because it's not reasigning the same IP to the same device.
The file /var/db/dhcp_leases show me the same MAC address and different IP, not freeing the anyone and thus, causing the server to stop giving IPs. We've currently managed to make a script to delete the leases db daily, but some days it's nt enough, any advise you could give us?
Some of the dchp_leases file:
ip_address=10.1.0.182
hw_address=1,0:26:bb:55:c4:e2
identifier=1,0:26:bb:55:c4:e2
lease=0x4cbda154
ip_address=10.1.0.181
hw_address=1,0:1b:63:b5:6a:de
identifier=1,0:1b:63:b5:6a:de
lease=0x4cbda0a3
name=MAC265
ip_address=10.1.0.180
hw_address=1,c4:2c:3:32:2d:23
identifier=1,c4:2c:3:32:2d:23
lease=0x4cbd9fe3
name=MAC265
ip_address=10.1.0.179
hw_address=1,c4:2c:3:32:2d:23
identifier=1,c4:2c:3:32:2d:23
lease=0x4cbd9f27
name=iPod
ip_address=10.1.0.178
hw_address=1,90:84:d:c4:72:2e

Thanks in advance,

This looks more like a problem with network settings and not any hardware problem. Try to setup your LAN connection again. Recheck your network service provider settings (thru default access page 192.xxx.xxx.xxx, using wireless connection): check whether DHCP server is enabled.
If you are using mac address filter, add mac address of your LAN card to the allowed addresses in network settings in 192.xxx.xxx.xxx

SF300-24 DHCP Server not responding (worked once but not again)

Tried to get the new firmware DHCP Server option working but after turning it off and back on it doesn't seem to give any addresses anymore.
Anyone else having troubles or success actually using the SF300 v1.4 DHCP Server?
I even tried factory default reset but no luck.
When I did have it working everything was good but the older Cisco Meraki would not get an IP address so I had to revert to an older DHCP server. When I tried again today by turning the older server off and the SF300 back on, none of the Windows machines that previously would work would get an address.

DHCP server not reusing expired leases

Hi,
I'm using DHCP server on SF300 switches for assigning IPs to guest clients.
DHCP lease expiration time is set to 1h, start address is 192.168.1.11 and end address is 192.168.1.20.
SF300 switch assigns all 10 IP addresses to different clients until pool gets exhausted. After 1 hour all DHCP leases become expired and I can verify this on address binding page.
Problem is new clients are connected after let's say 2 hours and they can't get IP address from SF300 switch because pool is exhausted and switch don't delete/reuse expired DHCP leases.
Is there any way to force switch to reuse or delete obsolete DHCP leases so new clients would be able to get valid IP address?

Hello there,
You can use the command (in privileged EXEC) clear ip dhcp binding X.X.X.X or just an * (asterisk) but if you use just the asterisk instead of an specific ip addresses, ALL bindings will be cleared, including active ones.
Hope this helps.

DHCP server not running on startup

Hello,
I installed Solaris 10u7 on my fileserver:
SunOS sunshine 5.10 Generic_139556-08 i86pc i386 i86pcI configured DHCP as follows:
dhcpconfig -D -r SUNWbinfiles -p /var/dhcp -a x.x.x.10,x.x.x.11 -d example.com -l 86400
dhcpconfig -N 192.168.0.0 -m 255.255.0.0 -t 192.168.0.1
pntadm -A 192.168.0.2 -m myhostname -y 192.168.0.0where x.x.x.10 and x.x.x.11 are my ISP's DNS servers.
At this point the DHCP server works beautifully. But when I reboot, the in.dhcpd process is not started (or quits immediately, I can't tell), and DHCP is:
DHCP server enabled.
DHCP server stopped.No combination of starting, stopping, or restarting the service with svcadm or dhcpconfig -S can start the server. The commands report success, but when I query, the serviceis enabled and stopped.
But if I just try running in.dhcpd manually, everything works again, until I reboot.
I'm new to Solaris so I'm not sure how to debug this. Any help would be appreciated!
Thanks!

Before the reboot, when everything still works fine:

Server not contacted on Port 587

Hello--This problem relates to the update of 10.4.7. Mail just fine before, repaired permissions before and after update. Used Mail and was not able to first send, error message (could not contact server on Port 25. Came to this forum and saw topics on possible problem with 10.4.7 update. Repaired permissions, reinstalled combo update, repaired permissions again, and now was able to receive email but could not send, was now getting error message that server could not be contacted on port 587. Have tried most of the solutions talked about here. Socks proxy off, moving Mail folder from Home Library to desktop, trashing plist. etc. We are able to send and receive mail using Netscape and my wife's school server. So the problem lies somewhere with Mail. Any new ideas on this problem with port 587. We count on Mail very much and getting it up and running would be great. Thanks for the help.

Sorry, This problem is with the iBook, have held off for the moment on updating the iMac.

AD, DHCP server not visible on network anymore

I've got a Domain with redundant AD servers - one physical, the other virtual. The physical is 32bit version of Server 2008, the virtual is a 64 bit version of Server 2008 R2. Everything have been working fine for about two years. I recently have been having
trouble with the physical server as it also serves as our backup server and our autoloader went AWOL on us. All that is back under control but shortly into that process I began noticing that the physical server kept dropping off the network - as in other computers
can't ping it, not can it ping other domain computers. It was a bit intermittent as it did finally connect after up and running for an hour or so - but that's not guaranteed either. It can see the internet so it appears to be a domain issue as opposed to a
network hardware issue.
I've looked through the system log but don't see anything that catches my eye.
Any suggestions?

Sorry for the delayed response. I thought I would receive email notifications, but alas.
The offending server (Glaurung) has a single network adapter - no pairing issues.
Nothing can ping either AD server - probably because it's not allowed by default as Jesper indicated. What I meant to convey was I cannot connect via Windows Remote Control when Glaurung initially boots up. The first time I try to connect, it does log in
but the service gets dropped and does not function for several hours (not sure exact time span). It does eventually work - as in the next day. Once it's back it seems stable.
I have not done any restores since initially setting up the redundant ADs (2 years ago).

Installing ios 5 ipad2 server not contact, check network

installing ios 5 ipad software update server could not be contacted. Make sure you network settings are correct. I don't know what this means.

I have same issue at this time. Perhaps server is down?

I upgraded from 10.3 and now "Connect to Server" not working!

yesterday I upgraded my co-worker's computer from 10.3 to 10.4, and for some reason he can connect to the internet but he can't connect to our server. We ususallly go to "Go to Server," type in our server address and then that window will go away and a new window will pop up showing that it is searching for that address. However, when I click on "Connect" the window remains and nothing happens. Thus we cannot connect him to the server, although he is able to connect to the internet with no problem.
Any suggestions?

what about trashing the finder preferences? did you try that first? I was thinking of trying that....

Window DHCP Server is not allocting IP to Voice Vlan

Hi,
I HAVE 3560 Switch, Over that two vlan configure Data & Voice respectively. Voice id Vlan 1 and Data Id Vlan 2.Routing is done on this switch and work as L3
DHCP Server is member of Data Vlan which is connected to another 3560 Switch L2. DHCP Server is reachable.On that both vlan configured.
Switch Port configure fr both Vlan ( Switchport access vlan 2 , Switchport voice vlan 1, Switchport mode access)
WHILE Connect any pc to port DHCP server assign ip frm Data Pool while Cisco Ip phones are not getting IP. OPTION 150 is configured in DHCP.
Over both interface IP Helper is configured and pointing to DHCP Server.
For testing point configure DHCP service on switch with voice pool range ;at that moment Cisco IP phone got the IP fron switch DHCP.
Now not able to understand why window dhcp server not assigning ip for Voice.
Both Vlan are in different subnet and having / 24.
Please guide

Replace DHCP server and now working fine. :)

I want to block DHCP Server

Hi i want to block on an ap where wlan clients are connected, dhcp server from the clients. bc the clients are getting the ip from my dhcp server. but when he also starts an dhcp server i ahve two server in my wlan. so i want to block dhcp ports on my ap.
i have tried it:
i made an port filter: port 67 and 68 (bootp server and client) then i places the filter on RADIO recive site. but then the client doenst get an ip. so i tried it only with port 67 or 68 it also doesnt work.
hope anybody can help me with this issue.
regards Bernhard

DHCP client requests are sent from DHCP client (68) to server's DHCP server port (67). Server replies using port 67 to client's port 68. All above are UDP obviously. So to block rogue DHCP servers put an input ACL 'deny any eq 68 any' to AP radio interface and this should work. Also remember that DHCP client for initial message exchanges uses 0.0.0.0 as src IP and 255.255.255.255 as dest IP so do not replace 'any' with your IP subnets. Hope this helps.

I keep getting the following error "server not found.....firefox can't find the server at http." when I try to log on to one certain website.

I was able to access this website prior to 2 weeks ago. I can access this website on other computers without issues, and I can also access all other websites on this computer.
The following is what is listed in the navigation bar when I get the error message.
http://iphantom.com/wisd/restricted.html?fn=Default&FP=l&ip=10.201.5157&ibip=66.206.97.9&ldu=l&re=0&bu=wps.prenhall.com
I noticed it says wisd/restricted, but I can log on to this website using my wisd computer without issue, and I get the same error message at my home/other locations. So I know that it is not restricted. I have used all the other suggestions "no proxy", shut down firewalls, but nothing has worked.
Any help with this matter will be greatly appreciated.
Thank you,
Cody
