PC not seeing the network and not being seen on the network

I set up a WRT54G to use as my network router. I have two pc's hooked up to it via wire, as the software used for the company requires this. 1 is my server, and there are no problems. I can connect to the Internet fine. The number 2 pc can connect to the Internet fine, but it can not see the network. Number 1 pc can not see the number 2 pc on the network. HELP!!! The work groups are the same, and I followed all the instructions hooking up. My laptop even hooks up to the wireless Internet. What do any of you think? Thanks

Check firewalls, and any virus suite that you may be using. Make sure that under trusted IPs you have check trust my network. You should be able to find that under personal firewall tabs in the virus suite.

I've used an external drive for time machine which has important files on it. After trying to back up my computer, it suddenly needed to be "repaired" by utilities. Now it's not being "seen" at all! How do I recover my important files off the drive?

If the external drive can be seen at all in Disk Utility, follow the instructions for repair here.

At present I have no power to the Gen 7, so need to get some power to it I think. I pressed the buttons as you suggested, but nothing is showing up at this point. Thank you for your response as the more I can rule out before I take it back the better I think.

Why can I not load pictures from a micro SD 64gb using scan disk adapter plugged into an Apple iPad camera connection kit. I have the iPhoto app but pictures not being seen on iPad. So incredibly frustrating. Apple please fix this.

Do you have a smaller capacity micro SD card to try? I seem to remember from past posts that users were having problems with cards larger than 32GB, however, Apple's page doesn't mention this.

LaCie d2 500GB Quadra Hard Drive Not Being Seen By Time Machine

Hello all,
I have a LaCie d2 500GB Quadra Hard Drive Not being seen by Time Machine hooked up to my iMac via firewire 800. My iMac is running latest updates etc. Have raised a support ticket and was given the following instructions by LaCie:
Posted: 08 November 2007 @ 00:00
Thank you for contacting LaCie Technical Support. Make sure the drive is mounting and you can assess files on it on your 10.5 system. If you can then you will need to reformat the drive to make it compatible with time machine.
Warning! All data on the external drive will be destroyed in this process.
Step 1: Run Applications > Utilities > Disk Utility
Step 2: Click on the LaCie hard drive's 'physical' entry, usually the third entry in the list
Step 3: Click on the Partition tab
Step 4: Change 'Current Scheme' to '1 Partition'
Step 5: Change the name of the drive back to what you would like it to be
Step 6: The format needs to be Mac OS Extended, with or without journaling
Step 7: Click on the Options... button
Use "Apple Partition Map" partition scheme on a PowerPC-based Mac.
Use "GUID" partition scheme on an Intel-based Mac.
Step 8: Click on OK
Step 9: Click on Apply
Step 10: click on Erase at the bottom of the screen, then confirm the erase.
The drive should start to be reformatted which should take only a few seconds and show up on the desktop with a new icon. Once it has you can then use it with time machine.
I have done all of the above and it is still not being seen. Anyone had a similar issue or got the above to actually work?
Thanks in advance!!!!

Ryan,
Check drive volume name and also the Computer name. Apple released a tech note recommending that both be limited to only the characters A-Za-z0-9 (no dashes, hyphens, or other special characters.
If you can, send the Apple System Profiler report to me at the addres in my profile. Imay be able to see something there. I have helped another user with similar problems, but with a LaCie USB drive. He got things working by repeating the recommended steps, and double checking everything.
As others have rported, this should work, so there may be something else preventing proper operation.
If the drive is usable from Finder, but Time Machine cannot use it, there is something related in how Time Machine is viewing the drive.

DVD 1270 not being seen in xp to install at start up windows 7

DVD 1270 not being seen at startup in xp to install windows 7. Boot order works - the machine sees a cd but not a dvd. Installed latest driver for lightscribe from this site. Also tried two other dvds - one a hp 1160 which works on another machine it sees the dvd on other machine running w7 but not on this new one - ASUS mthrbd P867-M Le. ASUS says it is the DVD and to try another. Seems like it may be a config issue. Any ideas? Thanks

Well, if the drive is good, then try a different SATA port. It might be that the OS is looking for the drive per the BIOS and it is not on the SATA 0 port. BTW: Does this motherboard have 6GB SATA ports? Do not use them for DVD drive.

Express not being seen on Airport Extreme Network

I have a new Airport Extreme connected to a PS running WIndows XP. Internet and all work well from PC, another laptop PC,my iMAc G5, and my MacBook.
When I plug in the Express it turns green than amber than blinks amber, and is not seen from the airport utility. I did the 10 second reset and still nothing but blinking amber.
A side problem is the PC's although seeing the Apple computers from the network, cannot connect to them.
Any help appreciated. Kevin

Mando2802, Welcome to the discussion area!
Try doing a hard reset or factory default reset on the AirPort Express (AX).

Time Machine server not being seen

I have an OSX 10.10 server and trying to get the time machine management for other units to back up to that system. The server can be seen and shared drives mounted by other OSX systems. However when I pull up the time machine on the remote computers they do not see the server to use as the storage for the time machine. Anyone have any thoughts?

I found that when I connected the system to the same subnet it was able to see the apple server okay and was able to get to the time machine. Word of warning time machine and home sync don't like being on different subnets even though it can ping and connect to the system via network mappings. I am really disappointed with Apple on this.

Airport not being seen

I was able to set up an AirPort Extreme that is being seen by my mac mini. However, my G5 does not see the AirPort Extreme network it created. I have tried to manually type the network in, change security settings, and numerous other setting changes suggested by my DSL service provider. I have about 10 hours in getting this to work and I'm quite at a loss.
Two things of note. As the G5 is my work computer and the mac mini is the kids, I decided to reset the AirPort Extreme and try setting it up on the G5 as I really need the internet connection. The G5 still did not recognize it at factory settings in the Airport Utility and the mac mini did.
Secondly, the G5 does see the 2 Airport Express's I've had in the house and the Airport Extreme didn't till I made a physical Ethernet connection. I would assume the G5 airport card is working fine then. It seems only one or the other can see the Express's, not both.
Can someone point me in the right direction to getting both these computers to see the Airport Extreme network. Thank you.
Duel 2.3 GHz PowerPC G5 Mac OS X (10.4.9) Airport Extreme 802.11n, Siemans 4100 DSL modem, 2 Airport Express

It looks like your correct. This morning I moved my G5 downstairs and physically hooked it up to the Airport Extreme, went back to factory defaults and redid the whole process. Disconnected it and the G5 recognized it wirelessly. I then moved the G5 upstairs (next to the mac mini) and didn't get the signal although the mac mini had a full strength signal. I then lugged it halfway to the base station (12 feet) and the G5 picked up a very weak signal (2 bars). Unplugging all the phones didn't help.
The signal on the AirPort is set to Automatic, it seems to like 11 as that is what appears in parens. I see where I can select a channel in the AirPort Utility, however should it be changed there or is there a way to change the channel on the G5 itself.
Thank you.

Ipod nano not being seen by computer, windows, 2000...

after over a week on the phone and attemting to get my computer to "see" my nano, and not being able to do so. and after going thru every trouble shooting guide given to me by apple i did get my nano to work.
I used every usb port but two, the two off the mother board, when i used one of them the nano took off and worked liked it was susposed to do, so...... you people who have this problem or know others pass the word use the mother board usb ports. nothing else.......

i resolved my computer, windows 2000, not seeing by i pod nano, by using the usb ports from the mother board. use no other usb ports, not usb hubs, or other circurt ports, just mother ports..................

Ei.cfg not being seen by windows installer on Windows 7 Home Premium 64 bit retail disk.

My problem is that the retail disk of Windows 7 Home Premium 64bit has no ei.cfg restrictions. Instead of choosing the correct operating system ID, on install, the .cfg
is coming from some where else installing a custom version of windows that is a different version of windows than on the retail install disk that I have a software key to. Even though it recognizes the key as windows 7 the operating system no longer recognizes
the retail disk it was installed from as the same version of operating system. It seems that there is a pre operating system install to a volume that cant see the ei.cfg file on the windows retail disk. It is something like Windows ME or MCE and it is hard
to get past because it acts like the operating system after install. It looks like there is a complete install of windows 7 but it is only a version of ME or MCE in the 100MB range installed to a partition volume. I am given a User account Profile within
Application Data folder in the system. The actual windows system in its entirety does not exist in the partial virtual operating systems. All the installs are to Partition Volumes on the Partition of a GPT Server Partition on a Disk
on the Hard drive. All Virtual.
Windows 7 Home Premium 64bit and 32bit retail disk is GSP1RMCHPXFRER_EN_DVD. The bios version on my Asus G75VX is American Megatrends version 206, V Bios version 80.04.97.00.13.N62G75500, EC version B14E140001. The operating system version is not the same
as the install disk. The boot configuration is; American Megatrends Bios Aptio Setup Utility installed. :\\?|GLOBALROOT\Device|HarddiskVolume1\EFI\Microsoft\Boot\BCD.Backup.0001 Software build after install is Buildlab 7601.Win7Sp1_rtm.101119-1850 Client install

The above information was taken after an install from the Microsoft Windows 7 64 bit retail disk purchased at Fry's and installed to my Asus G75VX. It is a Network Managed Client Server configuration that installs from the retail disk.

I have been dealing with this problem since the day I purchased the first notebook from Best Buy configured this way and it was not even an Asus. It was a Samsung Chronos i7. The Asus G75VX I have now is the third notebook in a row purchased from Best Buy
with the configuration right out of the un open retail box. None out of the three came with windows 7 installed. They had windows 8 64bit installed with the configuration. I purchased Windows 7 Home Premium 64 bit attempting to get around the configuration
problem.
My main concern is that I use computers to do my legal documents in court cases in the United States Federal Courts and I am a pro se litigator and I have been litigating a civil action since 2011 that is still open in the federal court. I am also legally
disable and covered by Federal Communications Act FCC Rule 255. This configuration has Telephone software and equipment, Management Software and equipment, and Networking software and equipment all covered within FCC Rule 255. My notebook is unusable for litigation
or personal use as a Publicly Managed Network Client Server. I paid $1350.00 of my Social Security Disability income for the Asus G75VX and another $216.00 for Windows 7 Home Premium 32 and 64 bit DVD and that is not counting a list of other things to
now have a personal notebook computer I have to sat down beside me in public libraries, Colleges etc. to use their computers to do my legal work. It is illegal and total wrong and it is a violation of the Bill of Rights First and Fourth Amendments and Title
VI of the Civil Rights Act of 1964 and the American with Disability Act outside of 255.

Ipad not being not being "seen" by itunes when plugged into mac book pro. Troubleshooting guide didn't help.

Hello, I just recently got my macbook pro (2009, 15 inch) repaired. While it was being repaired I bought an ipad and was synching it to a seperate computer. However, now when I plug in the ipad to the macbook, itunes does not see the ipad and the ipad does not recognize itself as being plugged in. I updated all my software/firmware/itunes software and restarted botht the computer and ipad. The computer I was synching it to previously died on me unceremoniously and this ipad has all my music on it. Any suggestions on what to do next?
-Dan

kmiddlet88,
yes, it could be due to nearly anything listed in your kernel extensions, startup items, launch daemons, launch agents, or user items above. Please check all of your installed third-party software to make sure that the versions which are installed on your MacBook Pro are compatible with Mavericks; uninstall every software package which isn’t Mavericks-compatible. After you’ve done that, boot into Safe mode, and see if you still get the beach ball of doom there. If it doesn’t appear there, restart normally and see if it appears then.

Aim buddies not being seen online

is there any chance my aim buddies are being seen offline all the time? its just.. I added people to my buddies and we talked once, but I haven't seen them again anymore, I can send offline messages to some, it says they'll read them when they go online, but some other contacts i can't send them offline messages.
now I ran tests with an aim account i own, adding it as a buddy on my ichat @mac.com account, and when I went online on the aim account it did show on my ichat account, and also sent some offlines messages and I did receive them, but its me in the same computer not like faraway as everyone else, idk if that matters.
now, do I have a technical problem? if so, how can I solve it?
or have my friends just not gotten back online, or they blocked me or what? :S
thanks for the help.

Hi,
By Default ichat does not fully log out of AIM when you shut down iChat.
This is partially so that you can get Off Line Messages when you start up your computer.
What it also does is start up iChat if You have it shut down but your Computer On.
Now you can (Sometimes) get a Message from AIM (AimSysMessage and Screen Name) asking if you want Off Line Messages.
If you reply or indicate NO to this they can only be restated on the AIM Website
Login to AIM web Pages then go to your Account Page the setting is there.
iChat can be made to Log Off line (Status as Off Line ) with a setting in the iChat Menu > Preferences > General Section
First Enable the Menu Bar icon.
You now have full access to "When iChat is Quit, Set Status to Off Line".
Now in iChat 4 and 5 you can also set your self to be Invisible.
You appear Off Line to your Buddies but you can see if they are Online/Available/Away and so on.
In any version of iChat in the iChat menu > Preferences > Accounts > Security you can set which Buddies see you as On line in various Allow Options an Block options.
Add to this if you allow Multiple Logins and also have AIM Forwarding to a Mobile Phone.
Now think of all those setting applying to your Buddies.
Some maybe Invisible.
Some may not have added you to their Buddy list and have Allow Buddy List Only (Or even Allow Specific People) set.
Some may have set not to get Off Line Messages.
Some may appear to be "On-Line" but are having messages sent to their Mobile Phone which they are not (able to) answering.
Summary.
Due to the number of variables that you have not been able to provide info on it is difficult to say if you have a problem.
Based on your testing I would say not.
7:33 PM Thursday; January 21, 2010
Please, if posting Logs, do not post any Log info after the line "Binary Images for iChat"
hey but even if all the things you wrote happened, if I do send them offline messages, they have to get them at some moment right? like I wouldn't be able to send someone offline messages if he blocked me, so if I send him offline messages he'll totally get them someday right?

Certificate Authority is not being seen by windows server 2003 machines

Good Afternoon,
We recently installed a certificate authority using windows server 2008 r2. There was an old certificate authority that had went bad and the role could not be uninstalled on the bad server. The new certificate authority works with windows 2008 machines but
does not work with server 2003 machines. Mainly trying to get the domain controller certificate. At first it was stating that the rpc was unavailable for the CA. I tried to delete the remnants under the sites and services role of the old server. The error
now it states that it can not find a certificate authority. As stated above the newer machines (Server 2008) can see the certificate authority and request certificates but older machines cant. Any assistance on what to do next will be greatly appreciated.
Attached is the error I receive when trying to request a certificate through the CA mmc.

It is possible to change the hash algorithm a CA uses to support XP and 2003 "out of the box" without the hotfix.
But it would be better to have two CAs in parallel - one using a more modern algorithm and a CA supporting a "legacy" algorithm - and the latter should only be used as long as there are clients that aren't able to validate the other algorithms.
On the CA, start regedit and locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\CertSvc\Configuration\<Your CA>\CSP
I am assuming that the Software CNG provider is used with SHA256 or higher (not with SHA1).
Change CNGHashAlgorithm to SHA1 and restart the CA service.
The setting can be reverted by changing the value back. All certificates and all CRLs signed by this CA will use the new hash algorithm after the restart.
