enter the password to unlock iphone backup, while restoring backed up iPhone

while restoring backed up iPhone data, I got below error "enter the password to unlock iphone backup". during back up, I did not enter any encrypted password.
I got one link from Apple, too long, but expended time to read and found, that one guy used his very 1st password for this account and able to go ahead.\


then I recalled and found my very password and used and perfectly I was able to do.


hope this will help.... thx

The security database on the server does not have a computer account for this workstation trust relationship, while logging in

while logging with domain account, to one of my VM I got the error "The security database on the server does not have a computer account for this workstation trust relationship", but I was able to log in with local admin account.
then I saw, it was joined to domain from computer properties.
but I noticed one junk value in system admin group users.
so what I did is removed the vm from domain to work group and then re-joined to domain,
then it was OK.


hope this will help some one.

To rename this computer or change its domain or workgroup, click Change. Grey out while changing system property

while changing the system property I got the Change button greyed out means disabled as below


Hence I was not able to change the domain.
finally I come to know that the server was promoted to a CA from add roles and features.
then you go and remove the role from manage computer from server management. this may needs restart.so after that it should be fine and you can change the domain.

Disassociate Project in LCS Dynamics AX

Hi, if you are using LCS, then you must be knowing about sharing the Project to other team members with in your partner link.

how u can disassociate that, when you do not need.
you can not delete as you will not be the Project owner.
so you can do so, by going to "Project Users" tool in extreme right and then delete yourself, else request the project owner to delete your name from the list and then onwards you will not see that Project in your list.

Update for Microsoft Windows (KB2999226) , Access is denied Visual Studio 2015 Enterprise installation

Guys,

while installing new VS 2015 Enterprise edition on Windows 7 machine, I got below error... it was strange and could not find any help from Googling...
finally saw the log file and search with the KB2999226, it was referring Windows6.1-KB2999226-x64.msu may be did not have access. I did that installation manually and hence it started working.

so manually install the file "Windows6.1-KB2999226-x64.msu" from "$VS folder\packages\Patch\x64" .
then run it.

Regards,
Sudhanshu

GUID Concept, how its created and format

very nicely explained... :)

A customer needed to generate an 8-byte unique value, and their initial idea was to generate a GUID and throw away the second half, keeping the first eight bytes. They wanted to know if this was a good idea.
No, it's not a good idea.
The GUID generation algorithm relies on the fact that it has all 16 bytes to use to establish uniqueness, and if you throw away half of it, you lose the uniqueness. There are multiple GUID generation algorithms, but I'll pick one of them for concreteness, specifically the version described inthis Internet draft.
The first 60 bits of the GUID encode a timestamp, the precise format of which is not important.
The next four bits are always 0001, which identify that this GUID was generated by "algorithm 1". The version field is necessary to ensure that two GUID generation algorithms do not accidentally generate the same GUID. The algorithms are designed so that a particular algorithm doesn't generate the same GUID twice, but without a version field, there would be no way to ensure that some other algorithm wouldn't generate the same GUID by some systematic collision.
The next 14 bits are "emergency uniquifier bits"; we'll look at them later, because they are the ones that fine tune the overall algorithm.
The next two bits are reserved and fixed at 01.
The last 48 bits are the unique address of the computer's network card. If the computer does not have a network card, set the top bit and use a random number generator for the other 47. No valid network card will have the top bit set in its address, so there is no possibility that a GUID generated from a computer without a network card will accidentally collide with a GUID generated from a computer with a network card.
Once you take it apart, the bits of the GUID break down like this:
· 60 bits of timestamp,
· 48 bits of computer identifier,
· 14 bits of uniquifier, and
· six bits are fixed,
for a total of 128 bits.
The goal of this algorithm is to use the combination of time and location ("space-time coordinates" for the relativity geeks out there) as the uniqueness key. However, timekeeping is not perfect, so there's a possibility that, for example, two GUIDs are generated in rapid succession from the same machine, so close to each other in time that the timestamp would be the same. That's where the uniquifier comes in. When time appears to have stood still (if two requests for a GUID are made in rapid succession) or gone backward (if the system clock is set to a new time earlier than what it was), the uniquifier is incremented so that GUIDs generated from the "second time it was five o'clock" don't collide with those generated "the first time it was five o'clock".
Once you see how it all works, it's clear that you can't just throw away part of the GUID since all the parts (well, except for the fixed parts) work together to establish the uniqueness. If you take any of the three parts away, the algorithm falls apart. In particular, keeping just the first eight bytes (64 bits) gives you the timestamp and four constant bits; in other words, all you have is a timestamp, not a GUID.
Since it's just a timestamp, you can have collisions. If two computers generate one of these "truncated GUIDs" at the same time, they will generate the same result. Or if the system clock goes backward in time due to a clock reset, you'll start regenerating GUIDs that you had generated the first time it was that time.
Upon further investigation, the customer really didn't need global uniqueness. The value merely had to be unique among a cluster of a half dozen computers. Once you understand why the GUID generation algorithm works, you can reimplement it on a smaller scale:
· Four bits to encode the computer number,
· 56 bits for the timestamp, and
· four bits as a uniquifier.
We can reduce the number of bits to make the computer unique since the number of computers in the cluster is bounded, and we can reduce the number of bits in the timestamp by assuming that the program won't be in service 200 years from now, or that if it is, the items that were using these unique values are no longer relevant. At 100 nanoseconds per tick, 2^56 ticks will take 228 years to elapse. (Extending the range beyond 228 years is left as an exercise, but it's wasted effort, because you're going to hit the 16-computer limit first!)
You can get away with a four-bit uniquifier by assuming that the clock won't drift more than an hour out of skew (say) and that the clock won't reset more than sixteen times per hour. Since you're running under a controlled environment, you can make this one of the rules for running your computing cluster.

How to install the updates required for MS CRM 2011, MS CRM 4.0

Sometimes when installing the MS CRM(2011 or 4.0), this needs some updates and its recommened by MS, as attached in the image.

So if the serever is not connected to Internet, then it could not be updated.
Sometimes the installation passed succesfully and installed MS CRM.
But sometimes some weired errors will come.
I will share this in my next blog.

So to get the updates, we can use the config files and the start the installation in the command prompt.
the list of the updates required for Server,srsConnector,email router are as folllows
The following URLS are for x86-based platforms:
The following URLs are for x64-based platforms:
####################################################################
while downloading the above make sure about your version of OS 64 or 32
config file for server and command
save the below file in Server_Config.xml
<CRMSetup>
 <Server>
  <Patch update="true">D://Server_amd64_ENU.msp(downloaded from 1st link)</Patch>
<Server>
</CRMSetup>
command
SetupServer.exe  /CONFIG folderpath\Server_Config.xml

like this the other two can be set up for srsConnector and the email Router
SrsConnector
save the below file in SrsConnector_Config.xml
<CRMSetup>
<srsdataconnector>
<Patch update="true">D://SRS_ENU_amd64.msp(downloaded from 1st link)</Patch>
<srsdataconnector>
</CRMSetup>
command
SetupSrsDataConnector.exe /CONFIG folderpath\SrsConnector_Config.xml

Exchange Router
save the below file in SrsConnector_Config.xml
<CRMSetup>
<Exchange>
<Patch update="true">D://SRS_ENU_amd64.msp(downloaded from 1st link)</Patch>
<Exchange>
</CRMSetup>
command
Setupexchange.exe /CONFIG folderpath\SrsConnector_Config.xml

hope this helps...
