Snow Leopard can't hold OpenDNS server settings from router

Since Snow Leopard upgrade (now 10.6.1), my iMac Intel has not been able to hold the DNS server address for OpenDNS that it should be pulling via DHCP off my router (linksys).
After a while the iMac simply reverts to the DNS server offered by my ISP (roadrunner). I know this because if I mis-enter a URL I get taken to roadrunner's redirection page instead of OpenDNS's the way it should be.
I can certainly hard-enter the OpenDNS IP addresses in System Preferences/Networking but that kind of defeats the purpose of putting these addresses in the router so they serve every machine on my home LAN. Machines still on Leopard are having no problem pulling the correct DNS server.
Some looking around suggests this may be a wake-from-sleep problem. Anyone agree? Is Apple aware?

1. Have you verified by looking in the network settings what dns your mac has, rather than "I know this because if I mis-enter a URL I get taken to roadrunner's redirection page instead of OpenDNS's the way it should be."
It seems strange that it would lose DNS settings obtained via dhcp, but keep the ip address.
2. How would it even be getting your isp's dns settings, if not from a dhcp request? Do you have them manually entered?
If after your mac loses the settings have you tried a renew dhcp lease, and do the correct hns addresses return?
This bears some further examination. Without more information I would disagree that this is a wake from sleep issue, but more of a network issue.
If your mac loses its network settings on sleep, it will wake and do a dhcp request. If the linksys is doing its job it will respond with the info you have told it to provide. End of story - there should be no way for your mac to get dns info from elsewhere that occurs to me at this moment.

How do I install Snow Leopard while keeping files, applications, and settings

I need to update my system, I realized that I need Snow Leopard (quiet late) before Maverick. My question is, how can I install it keeping files and all the data. I found this on Internet, does it work?
Install Snow Leopard while keeping files, applications, and settings
If you follow these steps, the installer will replace your operating system if one is already present, but will preserve your account information and personal files. You may have to reinstall some applications, however.
Insert the install disc (or the first install disc if you have more than one) into your disc drive. Restart your computer while holding down the c key. This causes your computer to start up from the install disc rather than your hard drive. When you see the gray Apple insignia, release c .
The Mac OS X installer should open automatically. Follow the on-screen prompts to read and accept the license agreement and begin the installation. When prompted to choose a destination disk, select your preferred location and click Install.
When the Mac OS X installation finishes with the disc, restart your computer. After the installation completes, a configuration program may begin automatically if you are installing for the first time. You will need to supply basic setup information for your computer.
Update your system software to ensure that you have the most recent operating system components. From the Apple menu, select Software Update... , and then follow the instructions on the screen. Often, you will have to restart your computer, and you may have to run Software Update multiple times before it can completely update your system.

That's why you need to back it up. You won't need to restore the backup immediately afterwards unless something goes wrong during the upgrade, but you'll need it later; the drive will eventually fail.

Snow leopard can't be installed on my machine.

Alright, here goes. Thank you in advance.
BACK STORY:
I have an Intel iMac. I've had it for a few years and it's always been awesome. I was running Leopard, and it was all gravy. So much so, that I even took it in to my Apple store to see if there was anything I needed to do to protect my machine, or if there were any updates for my machine that I should purchase. Dude at genius bar said yea, there is an iLife update and a new version of OS, Snow Leopard. He told me he would update my macbook (which was getting a new hard drive put in) for me and show me how to do it, so that when I got home with my iMac, I could do the same update to it. iLife 11 and Snow Leopard installed perfectly on my Macbook (my secondary computer). I tried to installed Snow Leopard verbatim what the Apple associate showed me, with his written directions. Popped in my disc, selected English, install began, got about 1/3 of the way through the progress bar and an error message came up reading "Snow Leopard can't be installed on this machine". Interesting. Apple store guy said I was good to go?
DIAGNOSIS FROM APPLE STORE:
I took my iMac back to the apple store the next day, with my macbook incase I needed to run a firewire from iMac to Macbook to transfer files. Dude tried to save some of my data but couldn't access it. He told me there was a OS conflict and he was unable to archive and install. He gave me a card with all the information for a data recovery service and told me I was SOL. Great. I took my mac in to make sure it was good to update, he said yes, and then I did it, in turn frying my main computer into a useless paperweight.
FUNCTIONALITY:
When I try to turn on my iMac now, it goes to a grey screen with an apple and a spinning gear. This screen stays up for about 45 seconds and then the computer shuts off. I've connected a firewire to the iMac and my Macbook and held the T key down in an effort to save my photos and music etc. The firewire symbol comes up on the iMac, but nothing appears in my finder on my Macbook like an external hard drive would. If I put the Snow Leopard disc in, and hold the T key, the Snow Leopard disc will show up in my Macbook's finder/desktop. If I put the Snow Leopard disc in the iMac and boot it up the computer just shuts down, even if I hold the C key. If I boot with the Leopard disc and hold C, the disc will mount and I can re-install Leopard, but I get a warning that all of my data will be erased in doing so. Obviously I don't want to part with 200+ GB of data. My last back up was about a month before all this so it won't be the end of the world but there are photos and other things that are recent to my hard drive with no back up and that I'd rather not lose if I don't have to.
BASIC INFORMATION:
I'm 24 with a bachelors degree and I am very comfortable with my mac. AKA you don't have to reply like you're teaching your grandma how to email.
My iMac IS an Intel iMac.
I have 47 GB of free space on it, plenty of room for an OS update.
Firewire ports are FW400 on both computers.
I had to archive and install Leopard once about a year ago on my iMac. Not sure why there was issue, but the problem was fixed when I did this.
So, do I have any options here besides erasing my hard drive? Has anyone ran into this before. Sorry for the rant. Thank you again.

Attach an external hard drive to the iMac. Boot from the Snow Leopard disc again, launch Disk Utility, go into the Restore tab, select the internal drive as the source, select the external drive as the destination, and restore. Then partition -- do not merely erase -- the internal drive, and see whether you can install onto it. If you can, use Migration Assistant to restore your data from the backup.
Not backing up = inevitable data loss.

Upgraded from tiger to snow leopard, can I go onto lion?

I have recently upgraded from tiger (I think) to snow leopard, can I go onto lion?
I have a imac 17" 2 GHz Intel Core 2 Duo, 1 GB 667 MHz DDR2 SDRAM, I think I bought it in 2007, I don't use it for much but a bit of browsing storing photos and music and maybe a couple of documents.
I have been told by some that if I go to Lion it would be a risk and slow the computer down, so just wondering what you all think.
Thanks in advance,
Rossi

According to unofficial sources, you can upgrade to 4GB RAM. I've done the same in my late 2006 iMac 20" which is offically upgradable to 3GB, but I stuck 2 x 2gb modules in anyway (mainly as I had one spare from my MPB). It's dead easy to do, I'm in the UK and bought Crucial memory which I've always trusted.
I believe the Mac will still only use about 3.3GB of the available 4GB RAM, however some people have reported better performance as both modules are the same size and this helps.
Probably worth getting 2 x 2GB given it's not that expensive. You can always keep your old RAM incase anything goes wrong.
I'd do this regardless of upgrading to Lion or not, the extra RAM will help.
BTW, regardless of a lot of the negativity, I love Lion, it speeded up my other 2007 MBP like it was a new machine. The iMac seems okay, although that is showing a few signs of some graphics glitches, but I don't think this is anything to do with Lion, more about overheating.
Best thing to do, is to clone your existing system (using Disk Utility or SuperDuper or CopyCloner) so that you can boot off that or restore it at anytime without losing anything of your setup.
Then clean install Lion (there are instructions about on how to do this, and create a bootable USB key). You can then migrate back your user settings from your clone to the Lion install. Or just upgrade Snow Leopard. Depends on whether you believe in fresh installing everything.
If you don't like Lion, or it's slow or whatever, you can always restore your snow leopard system from the clone.

I have a mac os 10.5.8, i want to upgrade to mac os snow leopard, can i keep all my files (documents, music on itunes) without backing up all the files first on a external device prior to the upgrade?

I have a mac os 10.5.8, i want to upgrade to mac os snow leopard, can i keep all my files (documents, music on itunes) without backing up all the files first on a external device prior to the upgrade?

I strongly advise against upgrading the OS without first making a backup. Were something to go wrong you would lose all your files without the backup. See:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:

Can you upgrade from 1.3.0.20 small ovf to 2.1 without migrating to a new server? It sounds like you can just adjust the server settings now.

Can you upgrade from 1.3.0.20 small ovf to 2.1 without migrating to a new server? It sounds like you can just adjust the server settings now. I am currently running 1.3.0.20 and I have enough to do with also needing to upgrade my wlc to 7.4.121.0 and getting the MSE up to 7.4.121.0 without having to stand up a new server if I don't have to. Please share any information you have in regards to your experience with coming from a version 1.2-1.3 small ovf and going to 2.1.
Thanks,
Andrew

You are better off standing up a new server. It's cleaner and safer..... you can always try to upgrade if you wish, but if things don't work out well, then you just wasted a lot of time. Snapshot the VM and export the floor plans, just in case. The ova is built around the DB size, so I don't know how well the DB will perform if you try to expand memory or drive space after an upgrade.

I want to upgrade my iMac to Snow Leopard, can I use the (DVD-Mac OS X 10.6.3) that I got with my purchase of the 15" MacBook Pro that totally died, and upgrade the iMac from that DVD that came with the laptop ? Thanks

No, that 10.6.3 DVD is system specific to the MacBook Pro.
You need a Snow Leopard Upgrade > Mac OS X 10.6 Snow Leopard - Apple Store (U.S.)
or if a MobileMe users > Apple throws MobileMe users a free version of Snow Leopard

I want to restore my iMac Snow Leopard 10.6.8 to Factory Settings

Hi,
I want to restore my iMac Snow Leopard 10.6.8 to Factory Settings but the problem is I don't have OS Disc because it wasn't shipped with iMac. Also, when I restart the system and press Command+R nothing shows it just starting as usual. Could you help me please?
Regards.

Command + r won't work with Snow Leopard (OS X 10.6) - it only works with Lion and Mountain Lion. Did you buy the Mac new - if so it would have shipped with 2 grey disks, one for restoring and one with the iLife apps and a few other bits. If these are missing you'll need to call Apple and purchase replacements giving them the serial number of the Mac. They will make a modest charge for this.
