I have received following message while i ran VLOOKUP over 25000 rows:

"Excel can not complete this task with available resources. Choose less
data or close other applications."

Two workbooks are used have 25000 rows.

And my computer configuration is:

RAM = 512 MB
Processor = 2.66 GHz
OS= Windows XP Professional
Office= Office2003
HDD= 40 GB with 8GB space available.


Please give me any help/suggestion/clue anything......
Your comments are really helpful for me.

Thanks All
Adnan
