Dears,

1- The VB script can obtain the computer name, localy or remotely, and set it as a string variable

2- the obtained string will be the input of function that will obtain the below mentioned formula based on the obtained computer name

the function may do the following:

if i have a string contains a mix of numbers and letters, i.e 09AD7786L, i need to generate the below

L@da68*36

where L is the last letter of the main text, @ is appended text, da is the reverse of 3rd and 4th letters but in lower case, * is appended text, 68 is the reverse of the 86 sequence in the original text, the 36 is the sum of all numbers in the original text

3- the string resulted after applying the formula, would be the local administrator password for that machine
