HELP!!! ghosty Network Problem

Hi fellas,
I work in a medium sized corporation and we use both IBMs and Macs. I recently formatted a Powermac G5 and installed Mac OS X.4 on it, the networking worked perfectly for that day but went dead the next day. Same happened for a powerbook G4 laptop I formatted thesame day. Though all the systems need to see themselves, but I am majorly interested in them seeing the file server which is a PC. I am able to connect to these computers from other IBMs and Macs, but I am not able to see any computer list on them.
These are the facts....
* the IP addresses are perfect because I can connect from other computers
* the file share option is working well as I can connect from IBM pcs
This is about the 3rd time I am formatting and reinstalling 10.4 on the G5 and having thesame problem, it will work for a day and go dead the next day.
Please any help will be greatly appreciated.

Help troubleshooting networking problem...

I apologize for calling this a "networking problem," I just don't know how to title it...
Basically, I'm looking for help tracking down an odd problem on my MacBook. It mostly manifests as incomplete web requests.
I'll try to explain.
I'll go to a website, which starts a browser downloading images and what not. Most times, I never get the entire web page. For instance, on this very page, the bottom of the browser (Firefox) says, "Waiting for images.apple.com" and the circle is spinning at the top. This unresolved request, whatever it is, is unlikely to complete.
Here's what I've tried:
1. Updating my wireless router. (Netgear G. I honestly don't notice this problem on other systems in my office, though.)
2. Changing web browsers. (It affects others, too.)
3. Creating Mozilla profiles.
4. Surfing in different Mac accounts.
5. Clearning browser caches/cookies/etc.
6. Turned on/off interference robustness on the AE.
I'm not looking for a solution (unless you have one). I am looking for some new ideas on troubleshooting the problem.
What's most annoying is that the problem is GASP intermittent. I may do one of the above things, for instance, and it seems like the problem goes away, but it comes back eventually. And it also eventually leaves for a period of time if I do nothing.
It feels like a networking issue, something outside the Mac -- wireless interference or something, but ... I just don't know.
Thanks.

I should have mentioned that I tried that.
There are a couple of APs in the neighborhood, one is a Belkin Pre-N with Airgo's chipset. The only reason I mention the Belkin is that there have been some news reports that suggest Airgo's wireless management degrades regular B/G wireless devices in the area. I don't know how true that is.
Anyway, it seems like I've solved it.
I surfed wired for about two days and was able to determine that the problem was related to wireless communication. Now, whether it was my Airport Extreme or my Access Point...
My Access Point was one that was given to me by a customer. She didn't need it any longer. It was used and I didn't really know how it performed. I can say that one of the things I did before all these problems started to take place was install that AP.
I replaced the AP this weekend. I decided I would just try a new one.
That seems to have fixed it. I do get the occasional hangup. (I do an awful lot of surfing.) Mostly I see the hangups now on pages that have an abnormally high amount of connections to external sources. An example of this is the dynamically generated Newsgator RSS feed page. This page goes out to all manner of websites to grab images and what not and I sometimes see hangups there, but that's about it.
This is good news. I was worried my Airport Extreme was to blame. But, you know, even my wife's laptop (PC) is performing better wirelessly. There was a problem in that Access Point. I had updated the firmware just the week previous to see if that would fix the problems I experienced, but no...
Anyway, I kind of needed to talk this out. I appreciate your help!

I try signing into iMessage and it takes about 45-50 seconds to do. When that happens it tells me there is a network problem. I am positive I don't have a network problem and I need help on this problem please??

I try to sign in and it just takes forever to do I try and try and do it over and over and it brings me the same results. Created a new Apple ID and when I did it still tells me there is a network problem. But the thing is I am still able to use the Internet I need help?? And it does the exact same thing for FaceTime so I don't know what to do??

Error -3259 is a network timeout error, usually. This article might help:

Help with Boot Camp Assistant network problem while downloading windows support system!

I need to download Windows support software, but just keep encountering a problem which says "Can't download Windows Support Software because of a network problem." What should I do?

I have the same problem. Anyone out there? Hello?

I have an iphone 4 with a talkmobile contract sim. I am unable te send or receive mms. I have spoken to talkmobile customer service, my phone settings are correct. Aplle say that it is a network problem, can anyone help?

I have n iphone 4 with a talkmobile contract sim. I cannot send or receive msm. I have spoken to talkmobile customer service, my phone settings are correct,Aple say it 8is a network problem!! Help!!

talkmobile is not a supported carrier. It's very likely that you have the same problem suffered by people who attempt to use T-Mobile in the U.S. MMS simply will NOT work because the network is not compatible with the iPhone. If you want full functionality, you will have to switch to a supported carrier.

3gs no service after updating to ios 5 tried network reset, reset all settings and even restoring from back been with out phone for 3 weeks now need help telus cant find network problem and apple has bad customer support please help!!!

my 3gs has no service after updating from ios 5 tried resetting network settings, resetting all settings and restoring from back up on itunes.
telus cant find any network problems and apple is difficult to deal with.please help 3 weeks with no phone and $70 a month not happy.

I have been having a similar problem for the last few days.Without warning the signal will just completely duck out leaving the device searching for several minutes before settling on a no signal message.
Sometimes restarting the device, toggling data and 3g settings or toggling Airplane Mode will set things right. However, a lot of the time I've been left without a working phone.
I don't believe this is a SIM issue, as I had to change my SIM only one month ago for another signal related problem. Again any help would be appreciated here as well.

"Software update can't check for updates because of a network problem" - help!

Recently, when I perform a software update check on the pulldown Apple menu, I get this error:
"Software update can't check for updates because of a network problem."
The only problem is that my network works just fine. I use the internet and get emails without any problem. But I can't figure how I can fix Software Update.
The only relevant updates have been for Glims and 1Password. Oh, and note the same problem trying to access the App Store; I just get a "Can't connect to the App Store" error.
Any hints?

I have to solve all my own problems.
The problem was due to Little Snitch. Once I upgraded from 2.4.0 to 2.4.2, my system works swimmingly again.
FIXED!

Odd Network Problem

Hi,
I have a strange network problem, can anybody help?
Basic configuration
I have three networks 10.190.0.0, 10.192.0.0 and 10.193.0.0 joined by a single server running Solaris 11 B64a with a dual port intel card and onboard intel card (e1000g0/g1/g2) each port is plugged into the gigabit port of a seperate Dell powerconnect switch.
they have ip addresses of 10.190.0.2, 10.192.0.1 and 10.193.0.1
The problem. I have connected from a remote machine through a solaris router machine on the 10.190.0.0 network to a computer on the 10.192.0.0 network (Beyond a switch).
The terminal works fine!
if I ping the 10.190.0.1 which is the other router beyond the box with the three network interfaces packets are not seen by the pinging box. However, if I snoop the interface on the three interface router I see both the ICMP echo requests and replies.
After a considerable length of time 10-30 seconds, a load of the packets suddenly appear on the pinging machine and then continue normally.
I would like to understand:
a) where were the packets during the time between the snoop seeing them leave and them arriving at the destination?
b) why does the terminal not suffer any delays?
We are suffering with a lot of strange network issues at this new site and I am trying to figure out if its the new dell switches, the solaris network stack or something else entirely!
Anybody got any idea whats going on?
Please Help I am baffled.

It may just be the pinging machine has received the packets, but it will not display them on screen until it has found a name for the remote IP address (or until it times out waiting for one).
Do you get the same behavior with 'ping -n' ?

Time Machine and Time Capsule - Failing with Network Problem

My problems with TM/TC have been ongoing for a couple of months now and I am going round in circles - need help.
This is the second post I have made, the first got lost in people suggesting the obvious - so I will try to be a little more specific if I can.
I will detail the current state first - i.e. where I am now - after I will list what I have done so far to get to this point.
Currently, my iMac (intel) is directly connected by Ethernet 1GB to the Time Capsule. The TC is then connected to a Netgear router which in turn is connected to Internet.
I have no network problems at all - internet connection is fine. the Netgear Router has the latest firmware version and is working fine. The porblems i have are nothing to do with this.
The time Capsule is in Bridge mode and getting a reserved dhcp IP address from the Netgear router.
The Time Capsule has been fully reset - i.e. power cable out, hold the reset button, plug in power cable (spark, spark), hold reset button, fast blink for 20 seconds or so, light goes out, release button.
I have re-applied the latest Time Capsule firmware.
I have renamed the disk on the Time Capsule.
I have renamed my iMac and deleted all the time capsule entries from Keychain.
I have re-installed Mac OSX and re-updated to the latest 10.5.6 release.
At the moment I have kicked off a backup with a lot of large files - like music folder, video folder etc excluded. I also have parallels and have excluded the disk image. I have 1 other 50GB disk image which is also excluded.
I am expecting the first initial backup will complete successfully.
I will then remove music and video from exclusions and allow them to backup. I am expecting this will complete no problem. (I do this because the upcoming problem will happen if I move away from the machine - and I dont want to sit there for 2 days).
So up to this point TM and TC have performed flawlessly. The issue that follows started happening before the 10.5.6 update after backing up with no issues for months. At this point I will be able to use TM to browse the backup and restore files. I will be able to mount the sparse bundle and browse files. Spotlight reports no issues and indexes quickly.
If I leave my machine after a successful backup and the hourly update kicks in it will fail with 'A Network problem' basically saying the backup has filed because of a network problem, but is not any more specific, logs show far too much to put the whole thing here, but the following is an excerpt

It goes on and on and is repeated every hour. For each one I get an error message on screen saying backup failed due to a network error. However I have tried a manual download over the same period set at an extremely slow rate so that it was downloading during this time and it showed no errors. I.e. the network connection from imac, through TC to netgear and out to internet - and monitored this while time machine showed these errors (i.e. at the same time) and this showed no connection problems at all and completed succesfully.
I know TM uses an internal address to do backups, but uses the same cable and network card to get the job done. I am simply removing the cable as a source of issue although I have also replaced this making no difference.
Applecare are involved and have so far been sent 2 sets of logs and so far have not been able to find the cause. New TC is on its way to try that, although they think it is something on the imac that is causing this.
Sleep mode is turned off although screen sleep is on. The tick is not in the box for putting hard drives to sleep whenever possible.
Now, after this has happened, and back at the machine. I restart both imac and TC. Try running a backup, spotlight starts to re-index - i.e. will mount the backup volume and start the index process, gets to about 90% then fails - again excerpts from log

Am I the only one having these problems? any help from anybody please...

Got the same problem with a 3 months old TC.
The replacement TC, does it work now flawless?

Screen Sharing/network problem seems confined to 1 volume. What's the fix?

I am having a networking problem on one of the volumes of my multi-volumed, three-Mac local area network, and I need a networking guru to identify the specific software file(s), application(s), or system configuration that is the cause of the problem. I have already spent several hours checking and re-checking the various hardware and system preference settings involved, and I have narrowed the problem down to a software corruption issue and/or system configuration issue on one volume.
I now need someone to identify specifically what the nature of the problem is, and how to eliminate it. I am not looking for a sledgehammer solution that says I should re-install all of the Mac OS X software on the problem volume. That may be held in reserve as a last resort. I'm looking for a more elegant approach, one that points out the specific corrupt files to remove without disturbing everything else.
Here's some background to set the context. I have a MacBook Pro laptop; a PowerMac iMac G5; and a PowerMac G4 hooked up in a network. All are running Leopard 10.5.8. All have file sharing and screen sharing enabled. Besides being able to connect to each other using registered users, my goal here is for each of the Macs to be able to share the screen of the others upon my demand. Since each of the 3 Macs can theoretically share the screens of the other 2, that makes a total of six possible connections. Five succeed; one does not. That's the problem. I am trying to determine why the iMac G5 cannot share the screen of the MacBook Pro.
The iMac G5 has no problem sharing the screen of the PowerMac G4. That connection is fast and immediate. But, every time that I hit the Share Screen button on the iMac G5 to try to connect to the MacBook Pro, I get a window with the blue barber pole spinning for two or three minutes as it is allegedly "Connecting to Mac Book Pro," followed by a window with a headline telling me that "Connection Failed to MacBook Pro." The text within that window goes on to say: "Please make sure that Screen Sharing (in the Sharing section of System Preferences) is enabled on the computer to which you are attempting to connect. Also make sure that your network connection is working properly."
Well, as I indicated, the PowerMac G4 has no problem sharing the screen of the MacBook Pro, so the Screen Sharing settings on the laptop are correct; and the iMac G5 can share the screen of the PowerMac G4, so its network connection is working properly in that regard. It is only in regards to sharing the screen of the MacBook Pro that the iMac G5 is not working properly.
The reason why I say that the issue must be unique to the one volume in question, let's call it "iMacG5 Music," is that another Leopard volume on the same computer has no problem whatsoever in sharing the screen of the MacBook Pro. Whenever I boot up in that volume, let's call it "iMacG5 JMB," it makes a network connection with a registered user name immediately, and it is able to share the screen of the MacBook Pro within a second of my issuing the command. In sharp contrast to the success of the iMacG5 JMB volume, the iMacG5 Music is unacceptably slow (several minutes slow!) in making a network connection with the MacBook Pro, and it always fails to share the screen of the MacBook Pro, preferring instead to take about three minutes to attempt the connection, before announcing its failure.
Since the iMacG5 Music volume makes an immediate network connection to the PowerMac G4, as well as sharing the screen of the PowerMac G4 the moment I ask it to, I have concluded that the hardware of the iMac G5 is just fine. The problem seems confined to the system software and/or associated networking files that are unique to the iMacG5 Music volume. I just don't know what those files could be, or where the problem lies, so I've issued this call for help.
Let me add one more little twist to this puzzle which baffles me even more. I use external LaCie Firewire drives as clone backups of my Macs. As part of my trouble-shooting process, I booted up from the cloned versions of the iMacG5 JMB volume and the iMacG5 Music volume. What I learned surprised me!
The iMacG5 JMB clone worked just fine in making a fast network connection to the MacBook Pro, as well as sharing the screen of the MacBook Pro. I expected that. What I did not expect was that the iMacG5 Music clone was also able to make a fast network to the MacBook Pro, as well as share its screen!
Yes, that's right. It's weird! Screen sharing works OK when I start-up from the clone of the iMacG5 Music volume, but it does not succeed when I boot up on the source itself! I was surprised to find that out, but I'm glad I did.
(Over the past few days since I executed the last clone, I did use Drive Genius to de-frag the source volume, and maybe that has contributed to the problem I am now encountering. But it's hard to say, since nothing else seems to be amiss.)
One solution, I suppose, would be to sync the clone back to the source. But, before I do that, I'm just wondering if anyone has a clue as to the nature of this problem on the source volume and what I might do to remedy it—short of re-installing the system software or restoring from the clone. Anyone have any insight to this problem?

CORRECTION #2:
Ignore the previous "CORRECTION" post.
Oops, excuse me, I wrote that sentence correctly the first time.
I was trying to point out that the ability of the iMac G5 computer to connect quickly and effectively to the PowerMac G4 when booted up into the iMacG5 Music volume was an indication (to me, anyway) that there is nothing wrong with the computer's hardware, nor its network connection ability, but that the problem lay somewhere in the files/settings used to connect to the MacBook Pro, which it cannot accomplish.
This is what happens when I get engrossed in one of these technical morasses and it ***** me into its vortex all through the night... time for bed.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." Tried suggestions I've seen on the forum.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." I've tried various suggestions I've seen on the forum but nothing has worked. TIme Machine worked fine for the last two years and just suddenly started having this problem every time. The only thing that was a little different is that the computer was off for a week while on vacation and then I added a large amount (20 GB) of photos. Now the requested backup size is 82GB, which is large, and process proceeds very slowly for 2-3 hours before failing with the message mentioned. I have more than enough available backup storage space for it. Before failing, Time Machine has backed up no more than 12GB or so of the backup. It fails during different files each time.
I've turned off the computer sleep feature, and I've checked that the NAS is set to never automatically power down. I normally backup over Wi-Fi, but I've also tried connecting to Ethernet and it still has the same problem. It's odd because I also have a MacBook Pro that is still backing up fine to the same NAS using the MacBook's Time Machine.
I am using an iMac with OS X 10.6.8 and an Iomega StorCenter ix2-200 NAS.
I have system logs that I can share if helpful. The logged messages vary a bit from run to run, but here are some messages that I've been seeing:
I always get this message near the beginning of the backup:
Event store UUIDs don't match for volume: Macintosh HD
I've gotten this messsage a number of times:

That looks like a problem was found with the file system (data) on the TM disk. I don't know the details, but OSX tried to recover it from the journal, and found extra data on the drive. Likely a result of the incompatibility mentioned above.

Something caused a disconnect. Can't tell from the log what it was.
I doubt it's a problem with something in OSX being damaged or corrupted, but reinstalling OSX isn't a major hassle, so might be worth a try.
To be incompatible with Snow Leopard, this NAS must be at least a couple of years old. It may be beginning to fail.
Contact the maker. See if there's an update to make it compatible with Snow Leopard. If so, that might fix it.
If not, or if that doesn't fix it, see if they have any diagnostics that will shed any light.

Officejet 7400 network problems

I am recently having problems with my wireless printer. Initially it periodically would go offline requiring powering off and on again. One of the solutions was to issue a static IP address which I have done. I also used wireless wizard to connect to the home network. The TCP/IP port is configured properly with correct IP address. The Officejet 7400 is listed as the default printer. I try to print something and it starts to print and then doesn't complete the page. At the same time the printer goes offline and I get "printer error" message. I'm not sure why the printer won't maintain a connection even with a static IP address. Any help would be appreciated.

This sounds more like a print spooler problem on the computer. Do you have Windows or a Mac? Try just turning off the printer by unplugging it while it is powered on and turn off the computer normally. Go over to the wireless router and unplug it for ten seconds. Plug it back in and watch for all the lights to come up and then turn on the computer and plug in the printer. This step should reset the print spooler on the PC, cover any printer problems, and clear up any network congestion if you haven't done this already. Also a good thing to do is to make sure the printer is plugged directly into a wall outlet.
I hope this helps! If not, what is the operating system of the computer you are using?

Hyper-V 2012 R2. RemoteFx. "The remote session was disconnected because there were network problems during the licensing protocol. Please try connecting to the remote computer again."

After a Installation from Windows 8.1/windows 7 everything works fine. For example Install updates and Software. If I connect the first time a remotefx card i can use RDP as well. But if i restart the host I get the mentioned error. What can I do. These
Hosts are not in a domain configuration. I tried it too but there was no difference. I didn't discovered any errors in the eventlog, too. Only an actviex error. But same errors occurs with a succsefull rdp session.
Also strange is if i start the vm without a remotefx card it works fine again. Only session with a Remotefx card aren't possible anymore.
Is there a bug or something. I tried it many times with the same error.
Maybe someone can help me.
kind regards
Tobi

Hi Tobi,
Thank you for posting in Windows Server Forum.
For a workaround, please try to perform the two steps.
1. Do NOT enable RDP 8 on the Windows 7 SP1 VM. You should install RDP 8 and update the ICs though.
2. Change the connection setting on the client from "Automatically detect" to "LAN"
Please check again below thread for information.
a. "The remote session was disconnected
because there were network problems during the licensing protocol" after enabling RemoteFX Windows 8 VM
(Please recheck answer by “dgeddes”)
b. "The remote session
was disconnected because there were network problems during the licensing protocol" After Installing RemoteFX
Hope it helps!
Thanks,
Dharmesh
