Can no longer connect to SMB server after upgrading to Lion

We have a MacBook Pro that was running 10.6.8. The user upgraded to Lion, and can no longer connect to a Windows 2008 file server. (We have two offices connected through a hardware tunnel, but i do not think this is the issue.)
We have tried to connect in the Finder (smb://[email protected]/). It asks for usr / pass, and then just hangs on "Connecting to server"
We can ping, have tested these credentials on other computers, and tried other credentials on this computer, to no avail. Furthermore, we installed a fresh copy of Lion on another computer, and successfully connected, so I don't think the issue is with Lion itself.
There must be something from the previous install that did not "upgrade" properly, but I don't know which file / setting it could be. It is system-wide setting, as we have also tried another user account on this same Mac.
We've also run Onyx to fix permissions, clean out all caches, etc.
Any idea what file i can change, modify, or delete?
Your thoughts would be much appreciated.
Thanks.

Yes, but the issue is not with Lion directly; there seems to be something with the upgraded system, perhaps a legacy setting or pref... I've scoured the system to no avail. I'm actually about to reinstall 10.6 - wasted too much time on this issue.
Thanks for your help.

Cannot re-connect to SL Server after upgrade to Lion

Hi all,
I faced a problem yesterday and I'm not sure what the reason could be.
First:
I have a Mini running SL Server for some time, all Open Directory users have mobile profiles.
For testing purposes I disconnected my MBA from the OD on the server, removed all mobile users except the local admin, and started the Lion upgrade.
After the successful (seemless!) upgrade I wanted to re-connect to the SL Server's OD.
That's were I'm stuck: I always get something like "Cannot connect to xxxxx. Error: -2100" (free translation from the german message)
Any idea what I was doing wrong?
Thanks in advance

Problem with connecting to free wifi after upgrading to Windows 8.1 from Windows 8

Hi
I had problems with connecting to free Wifi after upgrading my PC(Notebook) to Windows 8.1 from Windows 8. As I travel a lot within europe, I am used to being able to connect to Free Wifi(those that dont need a key or password to enter) but soon after downloading
Windows 8.1 I almost never was able to do this. I'd always get «LIMITED» even though the signal was strong.This was so fustrating,so much so that I reset my PC to clear it of Windows 8.1 and am now back to Windows 8.This is a shame because I was really liking
using Windows 8.1 and if not for this problem(which is a big one) I'd still be using it. If I download Windows 8.1 again from the Windows store what is the probability that I'll have the same problems?
Thanks Portozzygirl

More often than not when a device isn't working it is because the driver has become corrupted. Re-installing a fresh copy should help

Problems connecting to the internet after Upgrade from windows 8.1 pro

Cant connect to the internet after upgrading to windows 8.1 pro, what can i do to rectify this problem?
Thanks

Hi,
You can also try to install the older version in compatible mode:
Windows 8.1 Wifi showing "limited" or "No Internet Access"
Solution: revert your network adapter driver back to an older version
http://blogs.technet.com/b/dennis_schnell/archive/2013/08/31/windows-8-1-wifi-showing-quot-limitied-quot-or-quot-no-internet-access-quot.aspx
In addition, disable power management on your network driver:
Open Network and Sharing Center.
Click the Change adapter settings link in the upper left of the navigation pane.
Right click the network connection you want to enable/disable power management support on and click Properties .
Click Configure .
On the Power Management tab, clear the Allow the computer to turn off this device to save power check box.
If the issue still persists, please upload the event log for our research:

Can't connect ipad to wifi after upgrading to ios6

can't connect ipad to wifi after upgrading to ios6

Additional things to try.
Turn Off your iPad. Then turn Off the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi. (This is probably not practical in your situation.)
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.
If none of the above suggestions work, look at this link.

That poor wordpress site has collapsed in exaustion from trying to keep up with the 3mil hits a day
here is a "copied" version with credits for those looking for a solution to an annoying problem Apple should patch. (Yes, I'm aware of the irony of that statement)
July 18, 2012 · by Arthur Lockman · in Apple, Tutorials
After doing a reinstall of Lion a few weeks ago, I found that my computer suddenly would reject every VeriSign certificate that it encountered. Using Chrome, that meant that I couldn’t even access Twitter.com, because it thought that the certificate was wrong. I couldn’t login to the Apple developer portal, I couldn’t authenticate a device with XCode, I couldn’t make a purchase at Apple.com, I couldn’t download updates from the Mac App Store, and I couldn’t login to Mint.com, among other sites. I essentially couldn’t do anything that used a VeriSign certificate for SSL.
What did I do? I called my trusty AppleCare advisor, hoping for an answer. I thought that maybe they could help me figure it out. After getting to senior support, I was told to reinstall Lion, which I did to no avail. My case was then forwarded to the Apple engineering team, with 3 to 5 days to wait until I had an answer. I looked around, through my console logs and through Keychain access, and finally came up with an answer, and a solution to my problems.
It turned out that my solution was pretty simple. I had to delete a few files and reset one to its default setting.
Delete the files /var/db/crls/crlcache.db and /var/db/crls/ocspcache.db. These can be found using Finder’s Go >; Go To Folder menu (Cmd + Shift + G). This resets the cache of accepted certificates in the system. It doesn’t remove them, it just forces the system to rebuild the caches upon restart.
Open Keychain Access (/Applications/Utilities/Keychain Access). Select Certificates in the Category picker on the left side. In the search bar, type in the word Class. Look through that list, and find any certificates that have a blue + symbol over their icon. These are the ones you need to modify.
Select one that has a blue +, and hit Command + I. Click the disclosure triangle beside the “Trust” list to show the list of permissions. Now, what we need to do is to set this certificate to use the system defaults. However, for some reason, when you select it, it doesn’t save. So what you need to do is this. Under “Trust”, where it says “Secure Sockets Layer (SSL)”, change the dropdown menu to say “No Value Specified”. Then, close the window. It will ask for your administrator permissions. Then, open the info pane for that certificate again. Under “Trust” again, now set the dropdown that says “When using this certificate:” to say “Use System Defaults”. You can then close out of the info pane, and enter your password again. Do this for any of the certificates that have a blue + on their icon. There should only be one or two at most.
Restart your system.
This solution seemed to work just fine for me. All of my certificate problems have been fixed. It must be something with the OSX installer that causes this certificate issue. I’ll file a bug report. Hopefully someone looks into it and fixes the flaw in the OS. And, I hope that this fixed the flaw for you.
Addendum – a note on security:
This procedure won’t affect the security of your Mac. I’ve had some questions come in about that, and if anything, it makes it more secure because then sites that require SSL certificates can actually use them, unlike before where they might default to non secure connections because the certificate was bad.

After upgrading to Lion, I am unable to read burned DVDs. Any idea what is wrong?

While I was using Snow Leopard, everything was working fine; but after upgrading to Lion, my Mac Mini (2010) is unable to read any disks that have been burned. All store purchased disks work fine, but nothing I have tried has worked for the burned ones. Does anyone have any idea what may be wrong?

Well, I did notice a few things about the disk I used that were on that list. I'm going to try burning a new copy on a new disk that has few to no scratches, not mark on it, and keep it off max speed. I'll get back to you when it's done. That may take a while seeing as it's an ISO that I'm burning and it took a good 15 minutes at max speed.

After upgrading to lion Time Capsule is solid yellow

Hi
After upgrading to lion I am experiencing a lot of problems with time caspule
1. backup fail: it starts and than fails (error message and yellow warning triangle)
2. unable to connect to TC disk, neither from airport utility, nor from Finder
3. Airport Utility hangs while trying to manually modify configuration (rainbow weel).
After a lot of reboot, reset, disk rename, time capsule reconfiguration etc etc AND TC DISK REINITIALIZATION (ALLA BACKUP LOST!)
now backup seems to work and I can browse files in Time Machine
BUT
Time Capsule is a steady YELLOW and Airport utility says there is an error on disk (The disk is not working)
Can somebody help me.
This all happened after Lion installation. Not a problem before
Franco

Hi William
The disk is the internal Time Capsule Disk. It's a 1Tb model.
My iMac is localized in Italian
So I write here the Italian message and a possible translation
The first error message I get opening Airport Utility is:
Utility Airport ha trovato una Time Capsule 802.11n (2.a generazione) che segnala problemi
(AirPort Utility has found a Time Capsule 802.11n (2nd generation), which indicates problems)
If I press on "Continue" I enter a page that says
"Problema 1 di 1: Il disco Time Capsule non funziona"
(Problem 1 of 1: The Time Capsule Disk doesn't work)
"Si è verificato un problema con il Disco Time Capsule. Collega un disco rigido USB al tuo disco Time Capsule e utilizza il pannello Dischi di Utility Airport per archiviare i dati ed eseguire il backup."
(There was a problem with the Time Capsule disk. Connect a USB hard drive to your Time Capsule disk and use Disk Utility Airport panel to store data and run the backup.)
While if I go to the manual settings and I select the disk,
on the disk data info I have
Stato S.M.A.R.T.: Non funziona
(S.M.A.R.T status: Not working)
As I said before, apart from that problem, everything else (time machine, backups and file recovery) looks working good (until proven otherwise eh eh)
I don't know if to worry about the disk but I find suspicious that everything just started after Lion installation.
I called the call center and they just said to return the TC for disk repair (have to pay, warranty expired).
I told them about Lion installation fact and they said it looks like a coincidence but actually it is likely that after a disk initialization or a big amount of data writing the TC disk may break (WHAT ?!?) and the Apple guy even suggested me to buy an external disk that is less expensive and give less problem than a TC !!!!
(I can agree on that now, but I was surprised to hear that from them )
Thank you very much for any help.
I hope this info helps

After upgrading to Lion, my Canon 7d can not be found.

After upgrading to Lion, my Canon 7d can not be found. I have used the USB connection to connect to my camera for several years with no problems, until now. I have reset the SMC, by powering off the computer and unplugging everything for approx 30 minutes. There are no new drivers available and any assistance will be appreciated.

I was having the same issue after upgrading to Lion OSX. I searched the web and found many people had the same problem but no solution so...
I called Canon and they told me to run 'Image Capture' its part of the Canon Software Suite so you should have it and then try downloading the pictures like you usually do. I use 'Image Browser' and with 'Image Capture' running in the background it works perfectly now.
Hope this helps!!

Excel 2011 issues after upgrading to Lion

After upgrading to Lion, I cannot open .xls files anymore in Excel for Mac 2011. The files on my own computer work, but files that I receive via email cannot be openend. Does somebody know how to solve this? Thanks. Raymond.

Did that work for you? I was looking at that too, but was discouraged by having to use a sparsebundle given Snow Leopard had such great NAS support.
FYI to everyone else, I upgraded my ReadyNAS firmware to 4.1.8. NetGear indicated the following updates with the nre firmware, but it didn't fix this problem:
     New features and enhancements
     1. Added support for Mac OS X 10.7 “Lion”.
     2. Added warning when NFS access to home shares is enabled.
     3. Added a redirect for http://<host>/ip to https.
     4. Added enhancements to advanced AFP permission settings.
     5. Provide download links for exported users and groups instead of asking for email.
     6. Updated ReadyNAS Remote to the latest revision.
     Bug fixes
     1. Fixed javascript error in FrontView.
     2. Delay auto power-off if backup jobs are still queued.
     Limitations
     1. IE 6 no longer supported.
     2. Drives greater than 2TB are not supported.
I found this link which I thought had some useful information: http://carryflag.blogspot.com/2010/06/imovie-event-library-on-network-drive.html
Some people reported success with the terminal command:
     defaults write -app iMovie allowNV -bool true
But apparantly, after the Lion update, fewer people reported success with it. Still looking though... If anyone else has more symptoms to add, please let me know. I might try to use a sniffer program and see if I can pull a packet capture. That might reveal some info....
On another note, has anyone had any problems connecting to their Time Capsule in the same fashion? I had an idea of connecting a USB Raid Array to it and connecting through the TC, but wanted to know if anyone had any thoughts or experience with that.... Thanks.
