Hello Experts,

We have an urgent requirement to install a solaris t4-2 sparc server which is very old. It has 2 x 500 gb and 4 x 2 tb drives. We want to use 500 gb drives independently one to install Solaris OS and other for running some test app, the 2tb drives will be on raid1e for storing db files.

Now we are unable to boot to default os that ships with this t4-2 as it is old we are not sure if it will, so planning to install custom os solaris 11.2 and  we are planning to use as a test setup to create 3 ldom one for web app, one for db server and other as test

what is the best way to get this up and running?

Thank you in advance

I need to upgrade 2 of my PCs to Win10 and just want to check in with you Experts before I start, to make sure I do it correctly. Both are custom builds and all of the hardware on both systems are compatible with Win10. Also, for both systems, I have 1 SSD dedicated to the OS and programs only, while storing data files on several internal HDDs.

My questions are:
Do I just wipe the SSD clean, install Win10 and then reinstall software, or is there a way to only uninstall Win7,  install Win10 and keep the current software installed?

For one of the systems, I'm also upgrading the SSD from 250gb to 500gb so I'm assuming that for that one, I'll just replace the old SSD with the new larger one, install Win10 and install my software.

Thanks and I look forward to hearing from you!
I am trying to track down what should be an obvious question, but one which seems to be ignored on the 'Net:

When you enable an application-consistent backup in VMware, it configures the VMware Tools component inside the guest operating system to take a VSS Snapshot, which then engages all of the active VSS Writers to ensure that all data write activity has been quiesced prior to the backup.  This is all the easy part.

Now for the hard part: What happens if the system administrator never sets up shadowcopy storage within the OS?  Or, more directly, do you need to configure the operating system's VSS storage (i.e. vssadmin list shadowstorage) in order for this to work?  I have seen references that VMware handles the snapshot duties, which would seem to imply that you do NOT need shadow storage configured.  However, I can also see where the VSS environment within the guest OS would depend on it, and it might refuse to allow a VSS snapshot to occur without storage being available.  Which is it???
The laptop is Sony Vaio SVF1521B4E.
I have repaired it by changing the original defective motherboard (i5-3337U) with a cheaper version (Pentium 987).
The laptop boots and works normally from an extern USB with Win 8.1 live OS.
The laptop is stuck when I boot from original SSD with Win8.1.
No matter what repairing method I have tried, it says cannot repair Win 8.1.
I do no want to install Win 8.1 from scratch, because I need some programs/settings from existing Win 8.1 installation.
I do not have a previous saved session to returns/recover from that point.
I would prefer a kind of install repair, but everything what I have tried it does not work, it says always is a failure and cannot repair Windows.
Maybe it has to something to do with some settings/drivers related with previous motherboard or the boot (GPT) partition or I do not know, but I would like to avoid clean re-install of the Windows.
What suggestions do you have?
I have a Dell Precision workstation that needed a new RAID controller. The closest match available to the one in the system would not recognize the foreign drives and array from the old controller. I created a new 9TB array, downloaded the OS (Windows 7 Ultimate) to a flash drive. That's how Dell shipped the system. I can boot the OS with an MBR-formatted USB stick that sees UEFI. I have the driver for the RAID controller, and the computer sees the controller and the drives after the driver's loaded. However, it won't see a partition larger than 2TB, and won't format/install WIndows on any partition/space on this array.
Questions: Using Rufus or some other such tool, how do I put the OS on a stick that'll allow it to see and USE one large partition (or maybe two smaller ones, but use the entire 9 TB)? THANKS! :)

We have an iMac, 24 inches, from 2007. There is a Mac OS Lion installed on this computer. We want to install a newer version of the operating system and we tried 'Sierra' already but we didn't succeed. Regarding that, we would like to ask you which latest version can we install on this iMac?
I have Window Server Dell R 510.
The OS is Windows 2019 server.

Goal:  I need the server would be “cleaner” to make it a little bit faster (If possible, by using the built-in tools from the Windows OS)(Note: The RAM in the server is already 32 GB). Any suggestion?.

How to change the location for Documents, Desktop etc to a different drive

I added a second "Data" partition on my PC.  Now I'd like to change the location of Documents, Desktop, etc to that new partition.  I know how to right-click on Documents, choose, Location, and edit the setting.  But in the past I've had issues where I set it to D:\ and then couldn't change it to anything else later.

Is there a procedure for "Best Practices" in this regard?  e.g. create a Docs folder - d:\Docs and then use that for the location of the library file "Documents"?

My goal is to have all my data on the D: drive, so that if necessary later on I can re-install the OS without affecting most of my data.

Windows 10

Thank you

Upgrading Mac from 10.9.5

Can anyone suggest how I would go about upgrading a iMac OS from 10.9.5.

Is there a way of still getting the 10.10 or 10.11 upgrade form the Appstore?

I don't want to upgrade direct to the latest version and I don't know if you actually can even do that, but I dare say it is risky to upgrade to many levels in the 1 time.

Can anyone help me out with how best to achieve this?

Hey Experts!  Running into a rather odd issue and figured I'd ask the community of experts.

I'm using the Intelligent Provisioning > Express OS Install on a DL160 G10 server and the options available to install from is:
  • DVD Media
  • SMB/CIFS (Windows Share)
  • An anonymous FTP Server
  • Install ClearOS from internet

I don't have a DVD drive and the ClearOS isn't the OS I need.  I thought there would be a USB option but I don't see it.  Is there a way to add that option?  Is there an updated provisioning version I need?  I haven't run into this situation before and I'd like to get Windows Server 2016 on this server.

I appreciate everyone's help with this.

My laptop is a Dell 6500 lattitude &the OS is win 7 enterprize edition.  I also have an ext HD (F drive), a WD50 Passport which is nearly full of data.  Somehow the files I saved on the HD have got moved to diff places in the C and F drives while the files in the sub dirs, are readable wherever they are found, but ideally it is best if they can be returned to their orig.location.  I think I must have attempted to defrag the Drive using CC Cleaner program when there was not much space left on the drive.

Is there any remedy for this, using a Tool or fix manually?  Probably I could get another ext HD and copy all the recovered files.  thank u and regards.
Dell precision T5600 will not upgrade from Windows 7 to Windows 10. Does not have on-board graphics (Has a AMD FirePro W5000) but have tried several other non-AMD cards. BIOS updated when it was running Windows 7, Have altered several settings within the BIOS with no change, Have used Rotary and SSD drives, unplugging everything with in the box except the essentials so as to not cause conflict still upgrade fails with a SAFE OS error....I've done a bit of research and nothing on Dell's website or on other threads indicate it won't upgrade but still cannot....PC is out of warranty cause i'd like to speak to Dell's tech support to ask if it can upgrade or if they have run into an issue like this

Hi, I am upgrading our VMware cluster from 6.0 to 6.7. I encountered an issue with a VM guest with a very old OS (Open Suse 11.4).
VM runs fine on 6.0 hosts, but is not working on hosts already upgraded to 6.7.
I don't think is an issue with virtualized hard disk (LSI, Scsi controller, IDE controller, I tried all); system "hangs" immediately after kernel loading.
I checked this URL:


and I would like to understand if there is no chance at all.
Any suggestion?

Thank you very much
HP 8210 wireless printing




HP 8210 printer color prints have red color cast

My HP 8210 printer color prints have red color cast, any size, any image.

I exchanged all ink (with new) cartridges 1 by 1, reprinted to same (4X6 on 8X10 regular paper) - same issue.

Printed Swift Publisher 5 document - text/color background - 10 text blocks each with different color background - Results reasonably OK. Some slight color shift no other printing artifacts.    OS X Mojave.          

Seems the issue is only with photographs - any ideas why?
We can´t enable the options for Programmatic Access on Outlook 2016.

Tried all the registry changes via GPO and opened Outlook as admin but the options still stay grayed out.


DWORD: PromptOOMSend
Value: 2
DWORD: AdminSecurityMode
Value: 3
DWORD: promptoomaddressinformationaccess
Value: 2
DWORD: promptoomaddressbookaccess
Value: 2

I have seen that GPO is on "replace mode" and read that HKEY_CURRENT_USER  -settings are ignored on the "replace mode".
Is that true and how does it effect on this ?
Is the whole GPO created on wrong  way? I have never seen that before.
